alternative global calender for quick bulk changes

This is the feature I was expecting when I compared channel managers. Bizarrely, no one seemed to offer it. It's really quick and simple… it would save me hours of work and mistakes selecting days on the calendar.

I hit “create” a 3cm item appears with fields and “update” and “delete” buttons (like your rule sets page)

i select 1 or more properties from dropdown

i define a price and/or min nights

in individual dropdowns, I define a START day, month, year

Then END day, month, year

I tick which days of the week I want to change

I hit “update”

It updates the defined dates.

It remains as an item on list
So I can it again to instantly update future years, just change the year and ‘update’

I’d create an item for each of my seasons.
