Option to separate trackpad and mouse (natural) scroll direction?

I'm aware that there are separate mouse and trackpad options for natural scrolling in the settings.

However, it is the same setting, just one "variable" in the OS and that kind of defeats the purpose of the two separate setting. Becuase:

-If I use the mouse I have to go into the settings and turn it off.

-Then I stop using the mouse, remove it and then I have to go back and turn natural scrolling on for my trackpad

The two setting should be separate, retaining their options separately.

Is there a FREE and lightweight option for this to fix if Apple doesn't want to fix it please?

Like I was able to fix natural alt+tab with alttab application, maybe some pro mac users can recommend such free easy very light-bloatware free app?

But I think this request popping up quiet frequently so Apple should fix this finally.
