Global input quantize?

It probably is the way it is because it would be low on the priority list for needing any updates.
I don't even see why it exists. To me I would not want to set that and find my whole track was twisted out of shape and now un-repairable. My way of thinking it's much better to quantize after the fact so you can chose which setting best fits the song. But we each work differently and maybe there's a use for it I'm not aware of.

^^^This.  (I added the bold)

Yeah, in most cases that's right.  However, what I have in mind involves recording a lot of my song fragments (hundreds of unrelated verses, choruses, riffs, etc.) into one huge MIDI project, using the same auto-accompaniment style from my arranger keyboard, all at the same tempo and in the same key, so that I can then try out different combinations to see what song ideas work well together.  And for this kind of seamless blending, it has to all be perfectly quantized.  And since I know which resolution (1/8 with 50% swing) works well for this particular style, I'd like to have Sonar just quantize all incoming data at that setting, for this particular project.
 
This isn't intended to be anywhere near a final production, of course - it's just a way of auditioning things together in a sort of systematic, automated way.  An aid to composing.  Later, when the full song is sketched out, I'll of course record all the individual instrument tracks one by one.
 
Granted, this kind of project wouldn't be so necessary if I could simply remember how the second  song idea goes, while I'm concentrating on playing the first  one!  The first idea always casts such a spell on me while I'm playing it, I can never seem to remember how the next part goes (since, like I said, they've been completely unrelated up 'til now).  That's why I'm trying to automate the auditioning process. (the fact that I can't read music doesn't help either)...
 
 

Wait a minute, what am I thinking - for some reason I thought Input Quantize was just a temporary option which had to be chosen on a "per recording" basis, in other words re-selected every time you wanted to record.  Apparently no - if you set them once, they'll just sit there enabled for any ol' time you get the hankerin'.  Well.  That's good enough for me.
 
Then it's just a matter of either going through each of my 700 tracks and enabling the Input Quantize buttons one by one, or else starting from scratch and making sure the first group of tracks has it set correctly before cloning it out 99 times.
 
It might help to know that in addition to the 100 folders, I've also got 26 markers (A through Z), to accommodate the 2,500+ snippets I want to include in this "auditioning template" of mine.  It's going to take weeks.  In light of that, it makes spending a little time setting the Quantize buttons at the outset seem not so bad.
 
Thanks for the input, guys.
