Build Graphical Assets in Timeline, Save Somewhere Locally, Import Those Graphical/SFX packets into new Timelines

I create tons and tons and tons of social media content for multiple brands. I have designed graphical and SFX packs for each brand, and utilize the same “GFX/SFX” sequence at the beginning or end of the video as a branding mark.

For example, the end of each video for a brand will have the same fluttered logo come in, with a clicking sfx. Every time.

How do I save that or keep those assets available across projects? I would love to be able to have that saved locally and imported across projects, either into it’s own timeline or as a drop-in type of thing.
