Roof Rail covers with crossbars installed?

So pretty chuffed to source OE crossbars for the Vagon.

Installed them soon after - and now am like wondering why they don't have covers for the rails with the bars installed.

Wondering if there is a way to buy these or what folks have done to cover up the rails - as I'm not super thrilled to have an open area like that catching and gathering random garbage.

cheers!
