NEO full screen controllers - any options other than the RC2 ?

[Pongoglo]

Had my NEO for a while now and am still a massive fan but want to enhance my flying by adding a full screen controller that you can just turn on and go without the additional hassle of having to mess around launching DJI Fly and attaching to my phone. Prob is my other DJI drones are Mavic Mini 1 and 2 neither of which are compatible with the RC2. What I need is a full screen controller that I can use with all my DJI drones. My Mini 2 is fine for all my other flying needs and I don't want to replace it ( not can I afford) so if I purchase a full screen controller for NEO are there any other options that work with both drones? I think I know the answer but thanks in advance. Mark
