MMM-WunderGround would like to change width

[alang]

I’d like to use MMM-Wunderground to show a 10 day forecast in horizontal layout. By default it stays within it’s column region parameter — but I’d like to increase the max width for the 10 days forecast feature only (to utilize the area I’ve highlighted in yellow).

This would result in an L-shaped region, and I’m not sure if that’s possible. Is there any way I can do this?
