Upload the reusable pieces, intros, outros, b-roll, overlays, sound beds and call-to-action templates, categorise and tag them, and see how often each has been used across projects before you reach for it again.
Add Asset uploads one with a category and tags; search and filter by type. Each asset tracks its uses across projects and warns when it is being overused, so the same intro does not open every video.

Usage is counted per asset across projects, so the warning about overuse is a number rather than a feeling.
