Hi Mike
As you are saying such nice things about Scotflight, attached is a file that hopefully should do the job for you.
This file needs to be placed somewhere outwith Scotflight install and then you will have to create a scenery area in your Scenery library with a path pointing to this file. Also the new area will have to be above all Scotflight entries in your Scenery Library and also you then need to have the area producing your alternative objects above the new area created, otherwise the objects you want to see will also be excluded.
Trust this will work for you.
