Importing document doesn't maintain numbering format

[PosWeyb]

I have a set of instructions in one document and Introduction and Overview in another.

I imported the instructions (which have a multilevel numbering format) into the other document. It changed the numbering format from 1.1.1 to 1.a etc.

Anyway around that? In the meantime I am going to attempt to reverse the process..and see what happens.
