the incredible repetition feature

with  this option you can get so much material - lately ive been using the phrase pool, (i wish i could have the phrases broken up into 1 bar or a few beats instead of 4 bar phrases but thats not the point of this post) and dragging various phrases into arrangeent view then using repetition to let it cycle on...after awhile i take a snapshot and trim it out, but would be so nice to drag another phrase in after that and cycle that for awhile.

would be great so have a freeze function on an instrument track so that one could build a large segment using repetition, then snapshot it, trim it how you like, then FREEZE segment... and start building next phrase segment
