How to show multiple copies of a multigroup group by default

Hi,

I'm using the CCK3 multigroup feature and liking it. However, I need to modify it somehow so that it shows a multigroup twice by default, rather than just once.

For example, I have a group consisting of 'Name', 'Address', 'Phone number'.

At the moment, on opening the user form, the group is shown once, with the option to add more:

- Group 1

-> Name
-> Address
-> Phone

But I need it to show, on opening the page and without the user needing to add another group him/herself, two of the same group (or three, or four, or five... I'm actually going to make the number dynamic, dependent on another variable):

- Group 1

-> Name
-> Address
-> Phone

- Group 2

-> Name
-> Address
-> Phone

I've tried digging in the code of the CCK module, and have tried using hook_form_alter in a custom module, but haven't been able to do this so far. Can anybody more experienced lend some advice?

Thanks,

Matt
