Feature request: re-ordering elements in a multi-selection list

Is your feature request related to a problem? Please describe.
Sometimes I need to re-organize elements that I selected in a multi select list. And my elements are in a long list of a 1000 elements.

• in the list of checked elements, introduce the notion of drag & dropping

Describe alternatives you've considered
For now I need to uncheck my elements, search for them, re-check them in the correct order. It works but it is very tedious.
