Add Connection Request Button to CB List

I would like to have a small button allowing for users to send a Connection Request directly from members listing as opposed to requiring users to go to the users profile and then select Request Connection from the Connections Menu dropdown.

I have successfully created a webaddress field with the URL to request connection using the command and added it to my list
The problem is users have to populate this field themselves and they would need to know their joomla userid number!

My Question is do we have any way to populate fields with a default value when a user registers and add their userid into this string upon creation?

I know I can add a default in the sql table _comprofiler_fields but appending the userid in string is the tricky part!?

The user_id needs to be dynamic and change based on the user displayed. To do that place your URL in a delimiter field and replace "&connectionid=43" with "&connectionid=[user_id]". Example delimiter field as follows.

<a href="index.php?option=com_comprofiler&Itemid=2&act=connections&task=addConnection&connectionid=[user_id]">Add Connection</a>
