SoundID Reference Upgrade to Apollo X Integration - how many unique system licences?

Hi - I currently own a SoundID Reference for Multichannel licence, which allows me to run the plugins on 3X unique MacOS installs/user accounts. This is handy because I have multiple studios with Apollo systems and can licence 3X different studio machines. If I upgrade with the UAD Apollo X add-on, will this work with 3X installs/studios? Every studio has an Apollo X, and is successfully running the original (current) Sound ID licence.

Thanks,

Josh
