I want to use the word soilMoistureSensorPin, i.e. pinMode(soilMoistureSensorPin,INPUT); to set A0 to an input. I hope that question makes sense. With digital pins it is common to use int soilPin=0; is there an analogue for analog pins?

using a variable to store an analog pin number

Analog pins don't need pinMode. Just use, for example, analogRead(A0).
