In BTB, you can merge terrain elements into one area and copies of single objects can be merged into one group.
Click 'Edit Surrounding Terrain' icon, in the Terrain window select items from the left-hand side menu (Ctrl+Left Click to add an item) and press 'Merge' button. The selected elements will be merged into one area. You can rename this area if you go to the 'Properties' tab, but the name will not be exported from BTB, so it's mainly for your own convenience.
Merging copies of single objects is done in a similar way ('Edit Objects' icon -> 'Edit' tab).
