Merging sprites

[fugigoose]

Is there a way to merge sprites ? I have two seperate sprites in the same sprite chanel (just at different frames) Problem is, I have the fist group cycle through colors (by changing cast members). I need the second set to retain these members. I need to either figure out how to get the two sprites together of how to extend the orig sprite, but the keyframe is at the end ofthe orig sprite, so when i change the lenght the keyframe wont move. so either

-tell me how to merge two sprites in same chanel into one continuous sprite

-or tell me how to move a keyframe at the end of a sprite without resizing the length of it on the score

I have 50 sprites that are like this, so redoing it totally is out of the question

Select all the spites in the sequence, drag them to an empty spot in your cast, give you new film loop a name.
