Selecting grandmaster tests for a talent you aren't using

I just recently got Grandmaster for Magic and only noticed your request for a screenshot afterwards. At the moment I can't accept any of Lezzaro's requests since I finished them for the day but I'll see if I can get the next set of quests tomorrow despite already being Grandmaster.

If you're willing to take my word that I only just recently got Grandmaster Mage and that I haven't rebirthed yet, this is a screenshot of my Grandmaster Mage title with Holy Arts as my active talent. I got the last 8 or so seals required to become Grandmaster with the Holy Arts talent active.

Oh, my questions have been answered, however i will go into testing of it later. I do believe you can continue taking your grandmaster tests while under a different talent as long as you started it under the proper talent. That is what i need tested. But someone else can do that i think.
