Can I use either rally 200 pedal as a standalone rally 100?

I have a rally 200 system with both RS and XC pedal bodies. I have found that swapping them out is too onerous and so I would like to use them as a rally RS 100 and Rally XC 100 on my two separate bikes. Basically trade the additional cycling dynamics info with the pain of swapping the spindles out. Is it possible to do that or does using a single pedal require it be a certain side?
