SEP 12 Lic File(.SLF)

I have 3000 users licensed for our SEP Clients. We are on SEP 12.1.2.. I recieved 1 with 1200 users and another 18th 1800 users. My question is, can more than one .SLF file be installed on the SEPM Console to equal 3000. The way we purchased the License was a bit strange. Just want to make sure we can do this. Odd question, but I am not sure.

Any assistance is appreciated.

Thanks,
