Sorry, I was away for a few days, didn't have time to reply until now. The official Conky probably doesn't support this, just google the official docs and double check, but I don't remember anything like that.
The Conky source code is fairly confusing to me, I'm not used to pointers and custom data structres so I can't really make any quick changes to the flow of the program. I have to reinstall all the development tools first anyways, so I can't even try at the moment. Let me know if the official Conky gets updated though, I can update ours with any new features they add unless they make it incompatible somehow.
