Custom Scenery Exchange / Looking for a b&m support connector

I'm looking for a support connector which I thought existed but i didn't find it after looking in a few parks & benches. I'm looking for a support that connects two slanted supports on a quarter tile into a vertical support on a quarter tile. To visualize this I have attached two similar supports(one ends in a slanted support and the other is on the diagonal). This support has to exist somewhere right, so can anyone help me find it?

Maybe it exists but your best bet is to zero clearence the two different types of connectors onto the same spot, which are: vertical to slanted support connector, and vertical to diagonal slanted support connector. It might glitch just a tad but for the most part it'll be unnoticeable and get the job done!

I just noticed my attachment didn't attach. Here's how it looks with two supports zero clearanced and the kind of support I need but on the diagonal. This support has to exist right?
