@ steppi,
As I mentioned in the announcement of the last update to the Python program the version number (2.1.0) refers specifically to the Python project and it is not identical to the micro-controller version of OpenSprinkler with the same number.
Adding the feature you requested is on my todo list but because I develop the program on a volunteer basis in my spare time there is no set schedule for implementing it.
I actually prefer to make a separate program for each zone/station because it allows a lot more flexibility such as setting them for different days and I can turn a zone on or off by simply turning the program on or off.
