[Therion] Overview maps

Martin (or anyone else) On this complex example from the wiki, there appear to be different scale maps of the same cave. http://cachtice.speleo.sk/mapa_cj/template.html I would like to do this to highlight a very complex junction of cave. So in a map I can offset by using map_to_offset [50 0 m] below Is there a way to double the scale of this section, or have you done it by putting it together in another program, which is fine, I just do not want to waste effort if it is something Therion will do. thanks Andrew
