Question on modifying templates using the new Writer integration

I am trying to create/modify a new mail merge template using the new Zoho Writer WYSIWYG editor. I had to save the document before I was finished. 

Now I cannot figure out how to edit the template so that I can re-save it in the final version. I cannot open the template from Z Writer. When I click on the "Edit" icon in the template explorer in ZCRM it only allows me to edit the document title and description.
