Merge more than two polygon in one go
Merging polygons representing for instance mesh zones can help reducing the number of triangles, particularly small ones, and reduce simulation time. The version of ICM I am using can only merge two polygons at the time. I currently do the polygon merge as part of my data pre-processing before importing the data into ICM as I can merge more than two polygons at the time. However, it would be useful to be able merge several polygons in one go in ICM.
