Wled Hyperion Ambilight HELP

Hi everyone, I'm new to WLED, but I recently started a project to create an Ambilight system for my PC monitor using Hyperion. The LED strip layout in my case doesn't match the one suggested by Hyperion's settings because, in addition to the usual frame around the monitor, I wanted to add a light bar underneath (I've attached a photo) that would reproduce the same colors as the part above. Among the available configurations, I only found the standard frame and the matrix one. However, in the frame configuration, I can add gaps, but not overlaps. So I was wondering if anyone could help me. I don't know if this is the best place to find it, but I'd be really happy to be able to solve this problem.

Thanks :)
