Importing Animation Files To A Project

I have an animation project and need to move over a sample from a separate file to it. it’s separated to focus on the sample itself to add later. And it’s animated with 16 frames.

I’ve come to see so far that I have to copy/paste from one project to the other, taking up a lot of time. Is it possible to import the file so the layer and frames are automatically placed in the layer table?

This my first time doing something this advanced and I haven’t done much with this program, so I want to make sure I’m doing things right and easy.

Responses will be appreciated!
