Production - Media Usage of a Clip imported into another Project

Hello!

I am currently working on a production with several projects, one of which contains all the footage, while the others have different sequences.

However, in the metadata tab under "media usage" in one project, it doesn't show how many times the clip is being used throughout the entire production.

Does anyone know if it is possible to reliably check the media usage for a clip in a situation like this?

Thanks!!
