[SUGGESTION] Built-in Double-Tap (Hold/Toggle) in settings

[DiabloGane45]

Describe your suggestion
Not many old handhelds have many buttons to fit certain functions in. So why not make a built-in double tap configuration that you can access from the "controls" settings menu? This way you can leave room for other buttons, especially those you cannot fit into your current button layout.

Expected behavior
Example
Reload > Triangle [Double Tap Action] Sprint [Hold/Toggle]

Additional context
This was more in reference for devices like the PSP/3ds.
