DoD Contractor supporting 2 different agencies, can they have 2 working fully capable CACs?

Does anyone have experience with or know of a contractor supporting work at two (2) separate agencies (e.g. Marine Corp and Air Force) at the same clearance level? This is work as a Contractor, not a government employee (civilian). All work would be completed under one company. Hoping to be able to use separate CACs with separate contractor emails and access.

Thanks in advance

You can only have one CAC of each type. Possession of a duplicate CAC or ID card in the same category is prohibited. You can have a CIV, and MIL but not two CTR.
