Bernie, yes I think we can use a similar UI/UX on the app Runs grid for an assay design that has "Editable Runs" enabled so that we show the selected runs in the editable grid. The single Run Details edit panel uses updateRows, so it should be possible to make bulk updates to that same table via the EditableGrid. Note that we do not currently support "editable batch properties" for assay designs, so I would not include that in this work/change.
I put the dev estimate for this around 5 hrs. When you add in code review, manual testing, selenium tests, etc. I think that pushes the estimate into the 8-13 range.
Assigning back to Bernie for milestone/priority assignment.
