Yes I know, you need the new release that fixes it, I'm going to release it in few days (I hope).
Unfortunately it's not possible to add them by yourself, to calculate profitability the difficulty and reward for the coin is needed and I didn't find any public API with these informations available in internet, so for each coin you see now I brought up a coin server with a private API to get that info.
Looking forward to trying out the new release!
