Import Messages/Exchange items defined in Avro IDL in Capella

I’m defining protocols using Avro IDL and I would like to import existing protocols in a Capella project. In this way I can re-use the msg definitions and exchange items in the scenario diagrams of Capella. Does anyone has experiences with importing/exporting of messages defined in avdl or another format into a Capella project?
Thanks in advance,
