Thanks for the reply, i don't think the functionality is possible within simpleminingOS itself at this stage but i have emailed the dev to see if it is on the timeline.
My thinkng is that if simplemining.net has an API that you can use to change "Rig Groups" on your "Rigs" then this should be possible!!

Hi, i am wondering the same, did you get an answer?
I was using Awesome miner before and had that feature. Badly miss it.
