I'm trying to convert fx tracks to chains on multiple tracks or buses using the swipe feature. (In CV)
I can't seem to do it, is it possible? if so what are the steps.
Also trying to use swipe to delete convert chains on multiple tracks/ buses as well. Is this possible too?
thanks

No it isn't possible. Your best bet is to make a track template with your included FX chain and add those.
Your second option is to create the FX chain and hold down CNTRL + drag the FX chain to the next tracks FX bin.
 
The only thing I found possible is to add blank FX chains to multiple tracks using smart swipe to select multiple tracks, then hold CNTRL and choosing insert FX chains.

Thanks,
These are old projects I'm remixing from top-bottom so a delete / wipe all fxs in project feature would be handy too.
What about reset/ add multiple ions,  is this a feature?
I don't care for gear or instrument pics but use simple text icons for sections in CV (along with color blocks.) Some of these sections (eg 'Loops') can have 30 or more tracks, to be able to add/ delete multiple icons would save quite a bit of time & mouse clicks.
