When I open certain Excel or Word documents then I am always asked if I want to enable or disable
embedded macros.

How can I permanently active these macros (when I open the document later again)?

However I do NOT want to change the document file itself.
Other user who may have access to the documents as well should have the choice to
disable them).

I could imagine that MsOffice resp. Word/Excel maintains an internal list
where "always activate macros for docs" are entered and remembered.

If this is not possible:

Is there a way to always allow macros for me (=when I open them) ?
