Dropdown - multiselect filter need to click "Select-all" before and after search

I have a “dropdown - multiselect” filter which allow users to search word through a column. Whenever user search a word, they first need to deselect “Select all” before running the search, and then needs to “Select all” of the results returned. This is not a good user experience.

Therefore, is there a way to create multiselect dropdown filter where user can search word and hit enter to get all result rows instead clicking on “Select all” option twice?

Thanks in advance,

This is not possible currently. I can mark it as a feature request.
