custom analysis period

Hi all,

Is it possible to create a custom analysis period from an hourly .occ file or a list of 1s and 0's? The ladybug analysis period module does not allow detailed manipulation.

Perhaps there is another way to do what I need. I need to find a  way to create a custom climate-based sky that only includes specific hours. I could create this by creating a unique climate-based sky for every hour and then summing the data, but I don't know how to sum the sky files. The honeybee rad-parameters module asks for a specific sky file location. That sky file has a .cal file that I don't understand. Is there some way to create a custom .cal file that creates a sky file based on an hourly occ schedule?

Thanks in advance for your help.
