Experimental Value Input Request

Today after changing a value and reloading the nano many times I was wondering why experimental value input was not a thing? I know not every one is coding, but it could be super handy for those who are.

Hidden on a settings page, or the ag diagnostics popup could be three boxes or sliders. You could enter values that go to predefined but dead end variables in the nano. That way if your doing some experimenting you have some variables you can shove in quickly from the PC. Scale them to whatever you like in the nano and only have to upload to it once.

Also in the same regard have three output values already linked so experimenting is that much faster.

Or is there a secret mode I have not found yet?
