Flash CS4 or CS5 / Spreading frames out in timeline?

Hello,

I have imported a few animated GIF’s in flash. Each has a whole lot of frames. I am running the FPS at 35, and it obviously means that the GIF frames will speed up/slow down depending on how fast the FPS is. That is great, but is there a nice little trick to spread the frames out, without having to edit the MC and highlight a bunch of frames, and spread them out? If I only had one or a few of these, I would just do it the long way. Anyone know how to do this? Thanks!

I also attached a screenshot of me highlighting all the frames, preparing to move them over by one to spread out the frames. The first few frames are spread out already as you can see :):b:
