Repeat show every N weeks

[olivermeyer]

Is your feature request related to a problem?

Some of our shows repeat every 8 weeks, but Libretime only supports repeating shows up to every 4 weeks.

Describe the solution you'd like

The more generalisable solution would be to allow users to specify the repeat frequency of a show - similar to the way Google Calendar works, where you can repeat an event every N weeks where N can be any positive integer.

I took a quick look at the code and found RepeatKind defined here. If that is indeed where the options are defined, then a simpler solution to my immediate problem would be to add option WEEKLY_8 to this object.

Describe alternatives you've considered

So far I haven't found a workaround and I'm managing these shows manually, with all the problems and mistakes that entails.
