Add "Used X times" indicator to Media Replacement Comps in Project panel

Currently when a media replacement essential property is used, a new comp is created under a "Media Replacement Comps" folder. However, if you later change the source of this media replacement, a new comp is created but the old one isn't removed. In a large project, this could end up with dozens of unused media replacement comps.

With most comps that are in use, clicking on them in the Project panel reveals a "used X times" indicator next to the file's preview. Media replacement comps that are in use don't share this behaviour, and in fact are shown in the Project panel when filtering to show only "Unused" items. If you were to delete these seemingly unused items, then any media replacement property is returned to its default state.

I would like to request that media replacement comps also show the "used X times" indicator, and that any that are in use are tagged as such, so that they are correctly filtered.
