Multiple AD domains with different processes for each domain

We have an environment in 1IM with one AD domain connected through Active roles utilizing custom processes.  We are adding a second domain however we are looking to go directly to AD via the connector but we would like it to utilize the standard processes.  I have set up the connection and some of the sync/processes are working fine however, they are utilizing the custom processes for the second domain.  Is there an easy way to segregate the work to leverage the appropriate process (Custom or standard) based on the domain?  Any suggestions are welcome.
