There is a work-around for storing multiple approaches of different types in
the 430.

It involves storing each approach at the end of separate flight plans.

So if, for instance, you wanted to store both the GPS05 and GPS23 approaches
at KSHN, you would store two separate flight plans, both to KSHN. One would
have the GPS05 approach appended on the end, and the other would have the
GPS23 appended to the end.

I am not sure, however, if this method would reduce much button pushing and
knob twisting.
