And now we get to the meat of the problem:

I still content that Display Groups are the incorrect place to do this;
what you are doing is, quite simply, logical grouping (an action by the
user determines what group of elements to show). That said, it's
obvious that there's some capabilities you need that Zend_Form does not
currently support: the ability for setElement*() to affect *sub forms*.
This would allow you to call setElementPrefixPath, setElementFilters,
and setElementDecorators *once*, on the parent form, and have it
propagate to all elements in all sub forms. I think this is a reasonable
request to make.
So, if you'd be so kind, could you place an issue in the tracker for
this?
In the meantime, I'd suggest creating your own Zend_Form subclass that
overrides these methods to not only iterate over elements, but also sub
forms (let me know if you need help with this). The workflow at form
creation would then be:
* create elements
* create sub forms and their elements
* call the appropriate setElement*() methods
