Copy Calendar Grouping

[#1]

I'd like the ability to copy calendar groupings. It would make building a calendar a lot faster, since most of my groupings are 80% the same, with just one filter different.

• This function will be a great time saver.

I just came to add the same request, we need more upvotes on this people! We have some very complicated calendar filters and use calendars heavily, and it takes forever to recreate each filter when some have just slight differences.
