setting default font and DPI for SDDM

I’m wondering if I can get some control over the default font and dpi setting used by SDDM. I’m running openSUSE under VMware Fusion on a Mac with a HiDPI screen. When I enable the HiDPI setting in VMware my main Plasma desktop looks fine with my configuration but SDDM is woefully small and barely legible.

Thanks,
Grant
