How to easily copy/export/import macros between documents

I have a document with a bunch of macros in a bunch of modules. I want the same macros available in another document. Is there any quick way to do it besides going to Organize Macros and then going to the Organize sub-window (why is there an extra window?) and then recreating all the modules and then going to edit the macros and then going to each module in the source document and selecting all and then copying into the corresponding modules in the new document?
