Please Support a broader range of Multi-button Mice

I've been a long time user of better touch tool. But it seems to be pretty useless with mice with more than 5 buttons. Better touch tool simply does not recognized them. I've read in the forums that BTT will only recognize mice that the system recognizes. My request is to recognize additional mouse buttons. Here are a few mice that I use:

Razer Orochi
Razer Naga
Logitech G300S
Logitech Orboros

And a few more. Lots of mice and most gaming mice in 2020 are going to have more than 5 buttons, and it's not very good that such a great tool like BTT ignores them. I renders half of your mouse useless when using BTT. So my request if to support modern multi button mice like those above.
