The Home Dashboard and custom reports

I find the home dashboard to be really handy but the budget pane isn't very useful to me.

The way I manage my finances, there's only one budget category I need to keep an eye on and the relative weight of my mortgage payment tends to really distort the overall budget picture.

If I could just see that one category (or group) with the little line to tell me where I am in the month, that would be perfect.
