Slice output info

Hello!
Is there a way to get the info (position, dimensions, etc.) from the output slices instead of the input ones?

Slice info in Wire only contains information about the input slices, currently you can't get information of output slice transformation from within Wire.

What would you like to do with the output slice information?

Thanks! Wishlist it is then!
Output info would help with decoupling the input from the output, meaning that you can have full screen input slices, and scale it to the moved-around output. It would also mean that the positional output info could be used to construct transforms for the inputs.
Patch probably explains better, so adding one underneath. In Wire this behaves as expected, but when using it in the adv. output in Arena, you can better see the issue.

i would seconds this I have some used cases for this as well and I think I already asked in the slack. It would be cool to just have the same thing as the slice in but for the slice output.

I just came to find this out too. Being able to get the slice output transforms, means that you could way more refined altered mappings. For now I guess I can output a UV map and fake it, except I just tried it and its blocky, so I guess I can't render a UV out of arena at 16bit even when the project is set to that.
I'll give you my use example.
I have an LED processor taking a 1080p output and chopping it into sections of a wider than HD but only 200px high. Some time I might have a render already mapped to the led processors mapping, so wall sections stacked with in the image. But I might want to play some content across the whole width of the screen centered on the output screen, not where the input map is. Usually I do this in vvvv, and I can create many mappings and switch between, but as we don't have mapping switching either, and UV mapping ( the other way I've handled this previously) what are the options here?
