Custom Configuration of input sensor

I’m using a Rachio 2 unit with a 6600 liter underground rain barrel.
I have hooked up a water level sensor to know when my barrel is near empty.
The sensor is normally closed contact. I have hooked it up to the rain sensor input and configured it as a Rain sensor on the Rachio.
I get a rain warning when the barrel is near empty and my automatic schedule is put on standby.
My request is: Would be possible to allow user configurable input? In other words, I would like to rename the input and decide what action to take when the input sensor is activated.
Many thanks
