Premiere Generating Peak files every time I reopen a project / move computer (APPLE)

Hi!

Between 3 computers at work we work on the same project at different times for various reasons.

All working files are on our network as are scratch disks.

Problem I am having is that whenever moving between computers, or sometimes even just closing and reopening the project on thee same computer, Premiere wants to regenerate peak files.

And especially when working on multicam projects this slows everything down.

Often meaning we cannot work on a project till its finished doing these background tasks.

Please help, how can I make Premiere relink to the same peak files and not start again all the time?

thanks

Andy
