Automatically reference previous screen

Hi Guys,

I've got a section "contacts" which have a related field "notes".  These notes a viewed within the section editor via a related-records field, which also has the ability to "Create"

Creating, creates a new record in the notes section, the first field of which is;

SELECT num, CONCAT(first_name, ' ', last_name) fullname
FROM `<?php echo $TABLE_PREFIX ?>_nlb_subscribers`

Is there a way of having this automatically reference the contact from which you created the record?
