[Therion] How to produce outputs integrating various types of maps ?

Hello guys, The question is in the title... I don't remember having seen this already on the list, and I have been through the wiki with no success. So my problem is that I would like to produce a single output (typically pdf), including several maps, usually one standard map, plus one extended elevation, but there could be several of them. One way to do this is to produce svg, and to use an external svg tool to assemble stuff together. However the svg output is not always 100% perfect... and it would not solve all problems , like having a single legend, etc. Is there a way to specify a "mixed" layout ? Eric.
