Bulk-import of Circuit Terminations

[kusen81]

Currently when doing bulk import with CSV on Circuit Terminations one needs to know the Netbox object id of termination_id to import. The best way to do this (afaik) is to simply lookup the corresponding ID of for example Site object to accomplish the import.
However, this is somewhat impractical when handling imports with many different Sites. I have looked into YAML imports but it seems that the same ID is required in that case.

Is there some way to import Circuit Terminations in a more practical way? Also, is it possible to import dependent objects in one go, like for example Circuits and Circuit Terminations?

I am currently on v4.2.0
