Agentry / Work Manager 6.1 - Loop over a collection in an update rule?

Hi,

I need to create some kind of overview screen containing all the Notification texts like a general overview

I wanted to create a rule with the following structure:

CONCATENATE

- Header description and long text

- For each Activity concatenate description and short text

- For each item cause concatenate description and short text

- For each item task concatenate description and long text.

But as far as I know, Agentry doesn't provide a function that can loop over a collection and concatenate the values of each entry. The functions available are only able to return one collection item. Do you think this is possible somehow?

I will appreciate your inputs.
