Adding new data to a Multi Select Dropdown

Wondering if there is a way to Add new entries to the Multi Select Dropdown? So the added entry is available to be selected (or maybe auto-selected?) and remains on the list from then on?

It can’t be pre-selected in that component. the toggles will always load empty.

Whatever collection drives the dropdown, just add a record to.
You could use a modal screen with a simple form for that.
