Make last selection stick

Hello, I’m using the YMME version of the plugin for car batteries and I’ve had my staff ask if it’s possible to make the last selected vehicle stick on the results page? That way if a vehicle has several different engines they can quickly flip through each them and see if all the batteries are the same regardless of engine (without selecting the Year/Make/Model again for each engine.)

I looked through the list of plugin modifications but didn’t see anything that looked like it would do this.

Thanks!
