Specifying the import path when adding a proto file

I just noticed that Postman added support for gRPC! Unfortunately I need to import the proto file and it won’t work unless I can specify the import-path. I can do this on grpcui and get it running just fine but I can’t seem to the find the option to do so on Postman. Has this feature been implemented yet and if so where can I find it?

We’ve added support for this in the latest version of the Postman app, refer to this comment.

Anyway, it doesn’t work in my case. I uploaded a .proto, and added a directory for import, but still the same error.
