Currently, there is no "Select All" or "Deselect All" option available for array-type entity inputs in self-service action forms, requiring users to manually select each item one by one — which becomes tedious and time-consuming when dealing with large lists. We'd like to request the addition of a "Select All" / "Deselect All" toggle or checkbox at the top of array-type entity input dropdowns, so users can bulk select or deselect all available items with a single click, significantly reducing friction and improving usability for anyone working with large arrays in self-service action forms.
