It can be done using the "Custom Variables"
first of all make sure to have all the required fields in your "list" then go to your button/link and add custom variables like:
name=$cck->getValue('name_field');&lname=$cck->getValue('lname_field');
(replace 'name_field' and 'lname_field' with your own fields)
Now go to your form and click on (2) then choose variable -> url variable and configure (put your variable)
Hope this will help.
