Reverse engineer from multiple databases into single model

I am new user of Idera Data Architect tool. 

I have found a way to reverse engineer the single SQL Server 2016 database into data model easily. I am unable to select multiple databases in the reverse engineering option available in the tool. In the solution i am working on, entities and data is split onto multiple databases for performance/management reasons. 

My question is, is there a way where i can reverse engineer multiple databases and have a single main model?
