WPF: Is there a way to combine the geometries of multiple paths into a single path?-CodePudding

Long story short: I'm building a WPF app where the icons are handed to me using SVGs. I use InkScape to convert them to XAML. Problem is, they way they build the SVGs end up converting into multiple paths. Some of these icons they want gradients, which end up not looking right. See below for sample image and code. This icon in question is a building with an up arrow which is representing sending data elsewhere. I've applied an exaggerated linear gradient to show the problem. I would like the upper left "window" of the building to be orange in color to match what is happening with the outline of the building at that point. Just like the lower right "window" should be mostly blue. The upper portion of the arrow should also be blue.

I would like to take the paths in the code below and combine them into a single path that will end up being this arrow-window-building all in one.

How do I accomplish that?
