Active Roles change workflow, that triggers on a user logon event outside active roles

hello, 

so what i was trying to achieve here is, when a user object is created, it could be a while before they logon. Upon a logon, i wanted a workflow to trigger, with a filter condition of the logoncount of that user (workflow target) equals 1

then i have a script object that runs which adds the user to a group on a temporal basis for 12 hours. 

is there anyway to get AR workflows to trigger on that sort of event outside of actual AR?
