Tailor controller form displayed in a popup

Sometimes when I create a tailor blueprint, my form may only consist of 1 or 2 fields… for example a testimonial/review blueprint just has author and content.

It would be nice if the form for these could be displayed in a popup rather than being directed to /backend/tailor/entries/{uuid}/create

I think this is possible within custom plugins using this command

php artisan create:controller Acme.Blog Posts --design=popup

I was just wondering if this is possible with Tailor and I’m just missing something from the docs, or is it just not possible?

I’ve tried the following in my blueprint to no avail.

uuid: content_reviews
handle: Content\Review
name: Reviews
type: stream
drafts: true

design:
    displayMode: popup

and

uuid: content_reviews
handle: Content\Review
name: Reviews
type: stream
drafts: true
displayMode: popup
