It would be really nice addition to the drag/drop workflow if I could tag a specific preset as a favorite rather than an entire instrument or effect.
As an example, there are one or two Presence presets I use - the rest I don't (or at least not very often). But those presets are buried waaay down in the preset menus and if I favorite Presence as a whole, it just doesn't actually add any value.
Also, doing this would hopefully allow me to mark multi-instruments as favorites as well.
