Converting areas for mapped meshing

I understand that mapped meshing of areas requires that
an area is bounded by 4 lines. Is there some automatic
way of converting one complex area (=bounded by several lines) to smaller areas, each bounded by smaller number of lines?

Thank you for your hints!

Take a look at concatenation. From the help file:

If an area is bounded by more than four lines, you can combine [LCOMB] or concatenate [LCCAT] some of the lines to reduce the total number of lines to four. Whenever LCOMB is permitted (that is, when lines are tangent and are attached to the same areas), it is generally preferred over LCCAT. LCOMB can also be used for non-tangent lines, but a node will not necessarily be generated at the kink in the line.

To concatenate lines:
Command(s): LCCAT
