Need Help for Using Both Infinity dongle together !

I recently purchase CM2, I was using Infinity Nokia Best before. My problem is that When both keys are attached with system CM2 Didn’t work it gives error You must activate this software via Infinity Online Service.
My question is that is there any solution with I can use both keys together because it is bit hard to remove one dongle for using 2nd Dongle even though both dongles are from the same manufacturer.
