In iWork, you can link to a Numbers spreadsheet so that if the spreadsheet's contents change, so does every document using it. Edit once, change many. I want to do the reverse. I want to change a document's visual presentation and have that change reflected in every document using that presentation. If I have 5 documents, all of which use exactly the same style but different linked spreadsheets, I want to change all of them at once the same way changing a spreadsheet's contents changes every document referencing it.
