Control sample frequency in multisample elements

We should have a way to control the number of appearances of the samples in an element.

This is most clear in sound effects with crowds and people, where some are very distinct and suddenly appear multiple times in different places.

The only way to do it currently is to add an effect as a separate element, have a large first sample entrance range and have it not repeat, which seems a bit wasteful.

In the element playlist tab, if we could have a checkbox for “limited plays” which will take a sample out of the playlist after it played an X number of times, that would be great!

Thank you
