Reference set selector - replace with better interface?
I have account managers (AM) associated with companies, n-n. To select AMs for a company the first approach would be to use a reference set selector. However, this requires the user to "(multi)select, remove" and/or to open a separate form and "(multi)select, add". This is a bit much. A much nicer interface would be to show a multiselect grid with all AMs, highlighting the currently selected/associated ones, then let the user change the selection with click, shift-click or ctrl-click, then save the form. Is this highlighting 'on show form' possible? In a save microflow, I could then simply remove all associated AMs and re-associate the selected ones.
Have you looked at the Checkbox Set Selector from the App Store? This gives a complete list and allows you to check or uncheck as you need
