On the "Gearbox" sheet there is a single colored dot by each gearbox name. If the motor name on the "Motor" sheet has a dot of the same color next to it then it means that the given gearbox is compatible with the given motor. It is so you can immediately see what the gearing options for a given motor are. I can update my first post to mention that.

I thought about doing the mapping in reverse, that is, having each motor have one dot and map each motor to all the gearboxes it is compatible with. I decided against that as I think the average use case will be to first pick the right motor for the job and then pair it with an appropriate gearbox.
