You need a Map Editor which allows brushes/masks/multiple selection or maps created via script.
The first simply allow you to select a number of tiles in a pattern (e.g. the 6-7 tiles which make up a bridge), store them and paste them as one.
In addition, other than the base layer, you will not have objects on every tile. Map Editor tools come with a floodfill.
Some Map Editors have collision data saved for each tile otherwise you need a walkability grid. This does not have to be the same size as the tilegrid or simply YES/NO but rather a value to cross the tile.
Most Map Editors will not use enemy placement (unless it's a fix emplacement). Personally, I would position and animate these seperately.
Many Map Editors allow you to define a list of tiles which make up and animation along with framerate.
I couldn't get the hang of UME.
I am looking at World Artist which seems simple to use, powerful and has Bmax code.
