Can I use both licenses at the same time?

Hi All,
I’m nearly at the end of developing a game for VR, PC and Consoles.
I have a creators account and use it as a teacher and also for architectural visualization projects.
I have a Twinmotion free account as I was in beta tester.
I would switch to publishing account without loosing my Twinmotion privileges and continuing to use UE also for free visualization projects.

Ok with these premises what is best way to proceed?
I have to create a new account (to hold both licenses) or I can simply swith EULA?

I’d like also to apply for your funding program for game developers.

Thank you in advance for your help.
