MCell3: Can a molecule reacts with a surface?

Hi,

I would like to define a reaction between a molecule and a surface.

Lets say I have volume molecules A, B, C with a reaction as following.

A + B <-> C

What I want to do is that, whenever C hits the wall,

C is replaced with A.

Is this possible in MCell3?

So far, I could not find this option...!

Thank you!
