Configuration manager to offer choices when config staging folder includes files

Description of the need

Some configs generated on dev site have been added to the config staging folder on another site with the plan to import them.

Going to the Configuration Manager at admin/config/development/configuration/ the available options do not include option to display files in the staging folder and select specific ones to import.

The existing options don't seem to cover my use case to import a selection of new configs to a site.

Maybe I am not in the right place in the UI?
