How to create slim instruments for use on stage?

[mistadreamz]

I realised that I use lots of samples in my sets. Up to 500MB is used for Samples.
So it takes some time to load these sets. (about 10-15 seconds for heavy sets)
For our liveact I want to reduce this time and saved each set in a new project to get rid of unused Samples which is a great feature btw.
But some instruments like sampler use multisamples where most of them are not in use.
I dont play midinotes on stage. They are arrangend and I just change makros of the instruments with my controller.
For example in one set I just use multisamples from 1 octave and only velocity 127.
Can live show me which samples of this instruments are in use that I can delete the unused ones?
They are just copies in the project anyway and the originals are still in the library.
