Can I use external pools though? I'm pretty sure you have that option but cannot find a way to do that

Hi there!
Sure you can add your own pools. Just go to the 'Farm' section, proceed to 'Rig Settings', scroll down to the 'Mining pool' line and click on the green icon on its right. Then simply type in the pool's address.
