Answer to last question about updating Profiles . (i’m getting confused as to which question I’m answering..

If you save the profile from one document, then it can be loaded into other documents, and they will then use the same formatting as the original. This applies to the way each element and element+stereotype is printed: columns, widths, tables or inline etc, but not the content which each document contains. That stays with each document.
So, if you want to change the look of a family of document, just re-load the new Profile in to each one, and re-generate.
