multiple sound files

[johnchap]

My problem: I am working on a project which requires the first 30 slides to be synchronised to music; the next 30 are to be under manual control, with 'live' commentary, and therefore of indeterminate time; then the final 30 are again to be synched to music - but a different file from the opening. I can find no way to position a selected sound file as required on the timeline. I have seen references to synching a GROUP of slides (i.e. several slides highlighted together) but cannot find how to do this; if I customise the group to a given piece, it starts afresh with each transition.

Any suggestions to help me would be most welcome.
