Inverse Text on Copper without Bounding-box

Description

I'm trying to figure out if there's a way where we can put text on copper, but just the text as zero fill, without the bounding-box/outline.

Currently, as far as I can tell, when we place text on a copper layer, if we want the text to be knockout, it forces the knockout bounding-box border as well. I'm trying to get this to just be the text (etched into the copper). I'm thinking an option like "[X] No border/bounding-box" (or skip the negative, "[X] Border/bounding-box".

Steps to reproduce

1. Add text, ensure it's on a copper layer
2. Set to knockout
3. Fill
4. Witness solid fill within bounding box, and negative fill/keepout/knockout border.
