import text flow by reference

Hi All,

I wonder if a FM scripting solution could be developed to update text insets in a FM template file.
The scripting solution must have similar functions as those of "Import text flow by reference" FM command and be able to check Master page name. If some conditions are obeyed, header or footer of each page must be updated.
What are the scripting functions to use if available?

All ideas ans suggestions are welcomed.

Thanks.

JM
