Get Hierarchy Editor to bind schematic and symbol views

Hi,

I am looking for a way to get the Hierarchy Tool to allow me to swap in a schematic with a different number of pins than the original schematic, e.g., a cell with views 'schematic', 'symbol' that have 10 pins and 'schematic_fixed', 'symbol_fixed' that have 11 pins. The cell above it in the hierarchy would then of course also have a 'schematic_fixed' view that used the extra pin or tied it off.

This would seem to need the Hierarchy Editor to know to use 'symbol_fixed' when the hierarchy calls for view 'schematic_fixed'...but I have not been able to make that work.

I there a way to do this?

Thanks!
