how to control all shop lights from one motion sensor shop light
Code requires that you use every device according to its labeling and instructions (because the testing behind the UL listing didn't test it any further than that).  So your first stop is back to the labeling and instructions on the lamp, and see what it says about using the receptacle to control other lights via the motion sensor.  

Knowing Feit Electric, I suspect it does not permit that use, and the motion sensor does not switch the receptacle, and it is there to serve general loads like drills or trouble lights.   Or, their vision for this product is that you simply enable all the motion sensors and allow each light to decide independently.  

I am no great fan of Feit's reliability and would not miss an opportunity to return a Feit to the store and get something quality. Generally everything electrical at CostCo is the pinnacle of Cheese junk.  

If you really want to do motion sensor for the whole garage, they (not CostCo) sell individual "stalk" motion sensors, that screw into a junction box cover.  If you use the type which has a neutral wire, you can have 2 or more motion sensors for better coverage.  From those you power your lights.
