Advanced categories selection in ClockWheels

The clock wheels are helpful but need to be expanded. The selections from the algorithm menu are useless. If I decide to add in some "gold" tracks, older songs. They are not current, yet because I added them recently, I cannot separate them from a brand new song that was also just added. Please add in letter categories (A, B, C...). That way I can put 80s song in one category and currents in another, so that I can really create a proper clock wheel. Much like in Selector, you could then really program your station like a pro. If you put in ten letter categories, that should be enough for someone to really mix of their station using the clock wheels. Right now, I find clock wheel useless.
