We need the ability to add a Placeholder for Dropdown Custom Fields (Single and Multiple) and have them associated with that Custom Field at the point of creation (or even editing). As of right now, we have to manually edit/add the Placeholder text each time we add a Dropdown into a Form or Survey. This Custom Field should maintain the same Placeholder setting as in other Custom Fields and it should carry over into Forms and Surveys (but must be editable).

For instance, for a single dropdown, I prefer to include the placeholder text: "Select one." However, I have to manually type this each time I add a Dropdown on Forms or Surveys, instead of adding it once in the Custom Field settings. Similarly, for Multiple Dropdowns, I prefer to include the placeholder: "Select at least one." or "Select all that apply."

See the images below for the example.
