How to link worksheets in portal to users massively?

Hi all,

In Demantra, is there a way to link the worksheets users are going to see in Worksheet Collaborator to the users massively (in order to avoid having to log into the collaborator user by user, go to personalize, choose the worksheets to be displayed and accept)?

I have seen tables PORTAL_USER_CONTENTS and PORTAL_USER_CHILDPANES play a key role, but I really don't see how portal worksheets are listed there.

Any thought would be of help.

Thank you,

Guillem
