Inroads drainage SDB file editing outside of Inroads

I have two separate inroads drainage files that were created for two separate drainage systems (A & B) of a project. Now, I am trying to analyze them together since system B outfalls into a manhole in System A.

Is there a way to merge these two separate inroads files into one file in Inroads?

In the past I have been able to open the sdb files in MSAccess and do operations like merge/delete records. Ever since I received an update to MS Access 2013 and I am unable to open the sdb in MS Access. I could probably have IT give me an older version of MS Access and I can go back to my old method. 

However, I would like to know if there is an option in Inroads to merge two sdb files.
