Can we have an option to set the tile outline to stay to the grid

Hi im using the tile editor with slopes
The problem im having is that the tile pallet always resizes tiles if they are not perfect boxes like this.

This can be solved by changing the outline of each sprite in the sprite editor to not trim any of the sprite. My problem is this takes a while todo for each tile.
I was hoping their is a way to automatically set the outline trim to always be the full sprite so that it looks nice in the editor. Cause i know my designer is going to see this and have a fit
Something more like this. (here it is with the outlines set to be the full sprite size(note i had to set this manually))

Thanks for the help. Diggin the new editor just needs afew changes here and their

 

Yes this is something that is being looked at. Thanks for the feedback.
