Feature request for fixture / truss library and maybe even some custom curtains etc.

A way to make your own library with stuff you do actually have in your own posession (maybe even have a way to add the amounts of fixture / truss you have) so when you are designing you can grab your own fixtures. And whenever you grab more than you actually have they will show up on your report list with a note of extra rentalls orso? (but this is maybe a bit to far, making your own library with all fixtures and truss you have would already be great and have them grey out when you used your numbers)
