Help with Object Manager (not a bug question)

I have managed to build a simple box and a terminal with GMAX with FSX gamepack. I have no problem in selecting and placing the objects, both display OK. Just want to know how to display the friendly name instead of the generated hex name in the Object Manager drop down list when adding object to scenery. I tried adding descr name to xml file hoping it may solve the problem but cannot compile as this is not defined in BGLcomp.xsd schema for scenery object. :-zhelp
