You only have access to the blog object on that trigger so yes you could, but you would need to format the URL yourself. Examples as follows.
Joomla
index.php?option=com_content&view=article&id=[var1_id]
Internal
index.php?option=com_comprofiler&view=pluginclass&plugin=cbblogs&action=blogs&func=show&id=[var1_id]
