Is it me ? or does Flypaper not support this..

I have created quite a few presentations since I discovered flypaper...however there is one function that i wish it had, or maybe i am missing something..I would like to be able to create "groups" of events that can be moved forward or backwards in the time line without having to redo each and every instance for each element in that page..the concept would be similar to a mixing console that could re route specific tracks that all could be controlled by a master volume , instead of changing the volume individually for each track. Sometimes when i am working on a project I may want to change the time of a certain group of events in order to add or delete a particular section for my story... right now I have to change the time entry or exit for each picture or text and it can take alot of time...Any solutions to this?
