3616648 - Cloud ALM and Signavio Revision comparison?

When you synch a Signavio BPMN into CALM, it is set to Draft, and the latest revision is the same as Cloud ALM Solution Process Flow. We are looking to do a revision check between Signavio and Cloud ALM for a given process.  In Signavio I can look at the revision, but in Cloud ALM there is no mention of the latest synched revision.

Question: Does Signavio expose an API that lets us retrieve the current revision number (or the full list of revisions) for a specific Solution Process Flow so we can store it in Cloud ALM and detect when the two systems diverge?
