How to collect assets to be able to drag & drop into mulitple projects?

hi. I’m new to unreal engine and I’ve been making a bunch of little projects to test out things. It would be great if there was some way to have a collection of common blueprints, mesh, textures, sound and particle effects that I could drag and drop into my project. I have used the MIGRATE option to move things but it’s a huge hassle to open another project just to bring in one tree object or a sound… and then open another project for a texture… and you also have to clean up the folder structure if it’s not the same… with everything UE has thought of and all the great features it seem like a big oversight… how is this handled in something like a game jam situation where you want to have quick access things for rapid prototyping?
