Apply multi-selection of filetered items

[bgadiel]

Hi,
When filtering the full drop-down items with a search query (e.g: typing the letter 'a'), I am trying to select all filtered items (using 'Shift' key).
Problem is that the full items' list is getting refreshed after every selection and the search query is cleared, therefore I need to type the query again and again after each 1 item selection.

Is there a way to be able to multi-select the filtered results?

Thanks.
