Need cycle filling for an exact a range of frames

hi,

needed: cycle creation to fill a given range of frames.
Example: make a cycle repeat as many times as to fill from frame 100 to 130. No more, no less.

As it is now, as far as I can see, you can only either create the number of cycles doing the math yourself of overestimate and then erase the excess. Which is annoying and time-consuming.

thanks,
Josh

And make it so that it fills the odd number of frames up with a partial cycle.
