WTH can't entities be exposed to Google Assistant / Alexa from the entity settings?

Exposing/removing entities from Google Assistant and/or Alexa is clunky. There’s no search or filtering, and with a lot of entities, especially om mobile, it’s almost unmanageable.
Wouldn’t it be nice to have a toggle below the area-setting in the entity settings popup to enable/disable exposure to Google Home / Alexa?

It would also be nice if this was in a list view rather than a card type view.
