Blueprint selector of type similar to input.select

Hi,

I know we can do freeform text in a blueprint selector, but what I really miss while working on a few blueprints is the ability to specify a list of things that can be chosen as a selector.

for instance I have mqtt switch sensors that can produce left, right & both. I want to be able to have the input to be only be selected to be one of these three.

Seconded! This would be great to have.
