custom aspect ratio in firefly

I have image which is for 3d texture

I've setup 3d model's uv with that texture and aspect ratio is not square size it's custom size. 

I hope there's new feature we can use custom aspect ratio. 
or following uploaded image aspect ratio.

Firefly or a partner model? Maybe some day for Firefly, but when it comes to the partner models, Adobe would have no control over this.

gemini 3 nanobanana pro's  aspect ratio is restricted. 

nanobanana pro is possible to automatic aspect ratio but firefly doesn't support that feature
