Using the minimote to create the associations is fine, that’s popular.
The alternative is to temporarily assign the devices to the “Z wave tweaker” Device type handler and then set the associations with that. Then you switch it back to the original device type handlers once you have all the parameters the way you want them to be
Either way works, so it’s up to you which you find easier. But you may want to use the tweaker in the future to change parameters, so I thought I’d mention it.
