Can I reference/link a sub-process to another .proc file?

Hi, we're evaluating BonitaSoft in our company as a possible replacement for Bizagi. Here's what we want to do, but so far couldn't:

We want to be able to link a sub-process to a different file on the disk. The use case is: the other departments are mapping their process, and I'm mapping the Macro process as well the process from my department. So I want to be able to share a folder with them, so if they update their diagrams, the ones in my workspace get updated too. For example: I create a dummy "Marketing" subprocess in my macro diagram, and link it to "marketing.proc" in the disk. So whenever Marketing guys update their process/file I will have it updated on my end too.

Is there a way to accomplish this in Bonita?

Thanks
