GNS430 Without the IAF

Hello,

Here's a situation that keeps coming up: I'm coming home to SQL
and want to fly the GPS30
approach. Like many GPS approaches, this one looks like the letter
"L". The corner of the L
is AMEBY, and 5 miles later after that is the FAF, CUZUP.

AMEBY is not an IAF, but that doesn't stop ATC. Typically, from 40
miles out they say
something like "fly heading XXX when able direct AMEBY". Then when I'm
close, they'll
say "Cross Ameby at or above 3200, cleared for the San Carlos GPS30
approach".

Since AMEBY is not an IAF, it's not one of the GNS430 approach
choices. Which leaves
Vectors-to-final, but when you choose that, the guidance to AMEBY goes
away. Well, I think
the icon remains on the moving map.

The only solution I could think of was to cross AMEBY, and then
activate Vectors-to-Final.
When already on the approach, and already dealing with the precise
flying required on the approach.

Anybody got a better way?
