You have to set a Variable for each link you want to add a ID to, in the <head add this:
<meta class="mktoString" id="linknumber" mktoname="Link ID" mktomodulescope="true" default="1">
Then wherever the link is on the page add the ID with the Variable:
id="${linknumber}"
You'll then be able to add it as a Local Variable in the editor:
