Reduce Project feature from After Effects
In After Effects, you can select compositions in the Project panel and run Reduce Project. This command will remove all footage, solids, and other compositions that are not referenced in the selected compositions. It would be nice to have this feature in Premiere.

I would love that. in the meantime I guess the workaround is to copy the desired sequence to another project by copy pasting, thus reducing the footage in that project to just that sequence

It really would, it's a great feature in After Effects to keep on top of things! UPVOTE!!
