1600 x 900 missing from "Properties > Advanced > Remote resolution"

"1600 x 900" is available as an option, from a running session's "View > Screen resolution" settings.  But "1600 x 900" is not available as a "Properties > Advanced > Screen resolution" setting.

1600 x 900 not available here

Can it be added as an option?  It's the perfect size for the TV I'm using as a monitor.
