Simbrief Import Doesn't Work for Flightplans to Chartless Airports

Tried importing this flight here from Simbrief:

It doesn’t import.

I suspect it’s because NZFX (Phoenix Field) has charted procedures but doesn’t actually have the associated charts. (If you open NZFX up, you’ll see what I mean: Charts knows about the procedures and their routings, but doesn’t actually have the associated procedure chart)
