Presentation - Different Periods

Now we can put different periods on different slides in the presentation, which is great. But it could have some kind of "menu" for selecting dates, so that you can select several slides at once for the same date. I say this because now, in a presentation of more than 100 slides that I have, I now have to enter slide by slide to change the date, which makes no sense, the time it takes to do slide by slide, because now this month I have to put an extra month.
Or have an option on the slide itself, so that it always picks up the one referring to a specific date, choosing to mark it, or select it individually on that slide.
