SC4 Tool Question

[Squalled]

Right, I'm making some new mods for airports, and I'm using SC4Tools (From SimsZone.de) and I think it's great, but I'm having trouble making somthing I want.
I have worked out that if a Lot (ie. Maxis Open Grass Area) contains an exemplar (?) called Occupant Groups, then I can change which menu (ie. Airport, Parks, Education) the item appears in, and other files (such as the RMIP Grass) contain exemplars that let me change the Lots name and description.
All well and good knowing this, but the problem is that I can't find any files that contain all 3 of these exemplars for me to edit. Does anyone know any, or can anyone point me in the direction of a different editor that lets me choose which menu a file appears in, what it's name in, and what it's description is.
Thanks,
-Ben

The name can be given by one of three properties, Exemplar Name, Item Name or User Visible Name Key.
The description can be fiven by one of two properties, Item Description or Item Description Key.
For more information, read Names and descriptions of buildings and props.

If a property is missing (e.g. the OccupantGroups), you would have to add it.
For that you'd need either iLive's Reader, or the latest tool, SC4 PIM.
