You could use a Programmable Logic Relay....and program it to do what you need.
I used a Moeller Easy Relay.
I have 3 self service bays.
When any of the bays selects Foam Brush, an air solenoid opens on my foam brush pump.
Likewise for Tire Cleaner, and PreSoak
soap.
I used 9 inputs to control 3 pumps.
Programming was relatively easy. I didn't even need the cable/computer to do it. I just used the LCD screen and pushbuttons on the PLC.
