I'm afraid you will need to request for details of every ticket to get tech assigned. Meaning first search for tickets using your search query and then loop through the list .
Oh, that really stinks.
I know this is beyond the realm of this forum, but is there any guidance you can point me to that will help me accomplish this with power query and web help desk?
Also, do you know if adding the assigned tech to the ticket query has been requested yet by other users?
