Yes, would love this. Especially once Pinterest full integration is live. It’s mush quicker to add many posts from the same source with the same info, like links, hashtags, etc etc, and then randomise/shuffle them, then it is to manually placing them in a calendar.
Like, let’s say you make a post and send it to 10 Pinterest boards. I don’t want them going out all on the same date. But I also don’t want to manually make 10 of them. A shuffle option would mean I can make all 10 Pins in one hit, but make sure they are going out at different times.
