What your asking is something way beyond our control.
But hopefully Frosty can answered this.
I too wish for this feature.
We might have better chance to post for this wish on the official forums.
The game doesn't support plugins only skin modification and certain extent of moving some elements of the UI but not all.
Only Frosty and his team can make those features that we want.
