Possible for Keynote slide reordering like FCP magnetic timeline?

This will more clearly articulate what I want to do. For example, I'd like to move the selected slide above the last purple slide in the above group such that it moves the last purple slide in that group, down to the following group. So essentially slides 21 and 19 will swap places.

I suppose what I really need is to have count limits to how many slides or slide groups can be in the parent group so that Keynote would know if it should move slides in a group or outside a group.

Each parent group is a week and the purple slides represent how many classes are taught in that week based on an academic calendar; hence why I need a lockdown count for each parent group so this dynamic slide/slide group movement can work correctly. Otherwise moving a slide will just move it inside that group.

The idea is if I only meet a class three times (three agendas) in a week , then moving a slide or slide group into that week for whatever reason, would push down the agendas into the following week(s) for the entire document, except where I locked holidays and such.

Hope this makes sense.
