Save a Holiday?

Not sure if this has been suggested before, tried searching and didn't find anything so if it has just point me in the right direction.

I would love the ability to "save" the settings of a holiday in the in-game calendar. For example, if you create a holiday on a specific date, but then want to move the holiday to another date, it would be nice to have "saved" holidays to just place on a calendar without having to re-select the specific aspects of the holiday itself. Does that make sense?

Thoughts?
