Nope. If you want macro or script capability, you'd have to create your map geometry in something like 3DSMax or Maya. Then export it to .LTA format later and load it into DEdit.
Just understand DEdit as a 'composing/configuration' tool for setting up a world. Already during the past 6-7 years, game developing studios are more and more using other programs for building the geometry (3dsMax,Maya,..), as it would be 'reinventing the wheel' for a game studio to create such tools.
On the other hand, scripting is also not always good (based on my experiences),as you leave to much control to the script, and so you could have errors/problems that would be hard to track down.

Yup. But for that you need patience to work with a (compared to some current other game editors) limited editor. And you need to know/imagine how pratically you would build things in 3D. As example: many years ago, where even 3d-renderer where just simple cad programs, you could build things just with extruding, rotating and some more.
I do all geometry in DEdit, so you can deal with it, but you have to want to. Otherwise you need external programs. And for sure, for some very extraordinary built structures, you will definitely need the right tool, as you would be blasted to do this just with extruding or rotating.
