I hate asking questions that have already been answered, so I’ve spent several hours looking for an answer, but haven’t found one.
 
Here’s my question/problem…
 
I see that you can add a second miner by going to Rigs - > Clicking on the rig in question.
 
However, there isn’t an option to add a wallet to that 2nd miner.  From what I can tell, it uses the 1st miner’s wallet info.
