Ilok transfer

I bought the full version of pro tools 10 and then paid for pro tools 11



Both showup in my account history in Avids website



I'm a bedroom ITB guy- I'm looking for the most inexpensive way to go to a friends studio who doesnt have pro tools and record drums and save a session file and bring back to my studio.. I dont use 10 anymore and went with 11 and AAX



I was all in for getting the express since I don't need all those plugins just from drum tracking but it requires the mbox only



Can I buy a seperate ilok and transfer just my PT 10 thats on my account with ilok on my account site? I prefer not to take my ilok with my PT 11 there in case I lose it etc... Is this possible to do?



Thanks to anybody that can help
