Turbo Button Functionality

[persecom]

I use a G600 mouse. On Windows, I would use a macro that ran every 500ms that would do a key down and key up event while holding a button, effectively making the 12 side buttons into 12 turbo buttons. The main use case for it was in Final Fantasty 14, where holding a button wouldn't be treated as a repeated press. Is it possible to recreate this functionality using input-remapper?

I've noticed that repeat is similar to what I want, but it requires putting a specific number into the first argument. I would prefer it to be basically infinity, since there's no way to know how long I want to use an ability in 14.

Thank you for your time
