Multiple labels in one page with Smartforms

I have the following problem:

I get an internal table with n rows, and n is going to change each time the form is called.

I have to print a label, in the same A4 page, for each row. Each new label is to be located right under the preceding one.

Each label is to be composed of several secondary windows.

How can I do that not to have to actually paint as many labels as an A4 sheet will hold?

I mean, can I insert some code to paint a window n times in different places of a sheet, but actually paint it only once when creating the Smartforms, at the beginning of the page?

Thanks.
