New issue of having a movement that takes a set/reps structure, but has
varying reps per set.  Example is a 3 x AMRAP 2RM of Bench...your reps
may change as you fatigue and we allowed a dynamic entry for movements
like this.  a normal set/reps will be considered static.  Got the
add/edit to work for the most part, just need get the adapter to draw
the right item now...
