Distro has no way to condition assignment on how many accounts a rep currently owns. Teams running account replenishment motions, where reps receive new accounts only when their active count drops below a target, have to monitor and reassign manually.
Admins should be able to set a minimum account count threshold per rep. When a rep is at or above the threshold they're skipped in routing; when they drop below it they become eligible again.
This is the floor equivalent of Distro's existing cap, and the two together would give admins full control over both ends of a rep's assignment range.
