How do I import characters into a new project?

I’ve been making character rigs in separate files before planning to import them into the main scene files, but can’t figure out how to go about doing that. I tried selecting an entire character and doing the “Copy Drawing Object” option and pasting that on a new drawing layer in the main file, but I can’t figure out how to properly create individual layers for each body part the same way the original rig’s file had them, or arrange them in the right order so that the back of their hair isn’t in front of their head and so on. I don’t know how to go about creating template files or symbols for each character, either. What’s the best way to go about doing what I’m trying to accomplish?
