Tuplet entry in Sonar

Is there an easier way to enter tuplets in Sonar?
I remember Master Tracks Pro on my Atari ST was able do many kinds of them easily.
This morning, I figured out what a tuplet of 5:4 with sixteenth notes equals: Each note duration should be set to 192. I created a 20 note run of those in 4/4, so it's 4 tuplets of 5 notes a piece.

To get them, I entered 5 quarter notes, selected all of those notes, used the "Length" feature (under the "Process" menu) and set it to 20% (both boxes are checked)so then it's fit into 1/5 the space, or one quarter note.

Then I experimented a bit, and used the "Length" feature again, after selecting all 20 notes, and set it to 75% (both boxes are checked). So now it's still 5:4 tuplets, but with an overall tuplet value on those notes of 4:3, 4 quarter beats in the time of 3.
In the Staff view, the notes get a bit goofy looking, as it can't display the tuplets the right way, but it works. Seems like there could be a CAL script to do all this for me, but not sure how go about it. -Rob

It's Firefox. You can't make paragraphs here with newer than FF 5 (or something) without writing <br>.

About the actual problem: I'm pessimistic, but maybe someone wiser chimes in with a solution.
SONARs notation is so very basic. I'm sure many would say that what you've already done shouldn't be possible :o)

If you do a lot of staff notation entry, Finale PrintMusic has a tuplet tool that makes it easier to do then having to calculate the ticks.
