Yes, but beware. I've had multiple problems having multiple tickets in my name under the new electronic system. First, I bought a one day ticket last summer that I did not use. It is hard to explain briefly, but more than once, when I went to the parks, instead of picking the ticket I wanted, the system kept picking that one day ticket. So more than once, I had to go to GS to have the system change to the correct ticket. It was actually luck that I did it the first time. Otherwise I may have lost that one day ticket for ever. The one day also kept popping up later when I tried to make FP+ picks.
I don't know if this will help, but I have a situation where we have 5 day complimentary tickets and had to purchase 2 days to get free dining. I spoke with several CMs who said go to guest services before you try to enter the park, and they will prioritize which ticket you want to use first. They apparently can switch it back and forth.
