Can Purview recognize watermarks/labels applied via 3rd party tools?

Information Protection question here folks.

 

We have a customer who's currently using a 3rd party tool to classify documents across their business. Does purview offer any capability to recognize existing watermarks/labels in the documents stored in SharePoint so that we can use these existing marking to classify content in Purview without overlapping (the idea is to gradually depart from the 3rd party and adopt Purview) ?

 

Appreciate your thoughts !

 

Thank you
