When assigning a complex string to various layout tags, it would be nice to be able to split the string out. Example: map A01-12-32; if I want to place "A01", "12", and "32" in various parts of the page layout, I need to create three additional fields and substring the data into those three fields. If I could do something like this: <dyn type="page" property="name" substr="3"/> it would make the whole process much more clean.
