A couple of Mediabay Questions

Hi, being tagging all my Musical SFX libraries to work deeply with the media bay. I wanted to know if it is possible to:

  1. Exclude specific files from the attributes results.
    So, I have tagged a lot of files that I don´t want to see as a yes/no attribute, but I want to exclude the NO files as a default and not waste an attribute panel? can it be done? short of removing 3000 files from the directories?

  2. Save the trim point (or even better the snap point) of a file.
    Lots of files have start point all over the place, it would be helpful to trim the start or put a snap point to have them locked to grid more easily. And that info gets saved somehow for future use.
