Is it possible to use a template in FZ2 helper?

Question

Zend Framework

If I understand correctly, then FZ2 helper can be used to implement widgets, typical, repeating blocks of a site... If you need to use something else for this, correct me.
On several pages, I have the same block repeated, interacting with many models and displaying a rather voluminous html code. I would like to implement it, for example in helper'e.
Question : is it possible to use a template in a helper (as, for example, a controller uses a template) in order to substitute data into it and not clog the helper's php code?
