Is it possible to setup the cloud services account for a customer such that it will support multiple email domains for the cloud users?

I have a customer that has one dataminer cluster shared between two subsidiaries in two different locations, such that half of the agents are connected to one domain, and the other agents are connected to a different domain.  Therefore some users have emails on the "@company1.com" domain and the others are in "@company2.com" domain.

Can we tie the users from both email domains into one common dataminer.services cloud account such that users from either email domain would be able to access catalog and deploy artifacts to the cluster?
