Expand Background Image through Section Separator (Instead of Solid Color?)

Hey guys -
So I’m working on my first site with your Cornerstone builder, and I’m hoping you can help me easily achieve a look that I am working on. See this image below:

Is there a way to extend the section background image to the bottom of the section separator using the builder?

Put the bottom angled separator on the section below with 24/7 (not the top section with OUR PLUMBING SERVICES).
Then use a negative bottom margin on the top section (or a negative top margin on the bottom section) to overlay the top section over the bottom section (so the top section background image then extends down “behind” the bottom section - and yo don’t see any gap).
Make sure the top section has a lower Z index (eg. 1) than the bottom section (eg. 2) so they stack in the right order.
