Using Drupal for some years now, it's so cool! But there's only one thing I'm missing: multiple sets of CCK-fields. ideas?

Hi guys!

I'm really loving drupal! So far I got nearly all my goals achieved. Up to one...

There's only one thing I'm missing: A way to define a set of cck-fields whereas the set is able to be multiple

short example:

I've got a section in a webpage that supplies press-texts as PDF and RTF format.

In drupal I'm only be able to create single cck file-fields and make them multiple itself.

In other CMS like Six-CMS there's a way to define 'custom-field-sets' that are enabled to be multiple.

So I would create a 'custom-field-sets' with 1. file-field-PDF and 2. file-field-RTF and make this group multiple

In Drupal I didn't found a way to get his work.

any ideas how to get this problem solved?

would be soooooooo nice :D

greetz,
