Hello again lubyou,
I appreciate you using the forum and my only goal is to help you get a solution to your inquiry.
I am a former technical specialist but I am not familiar with all products. In our forum if a fellow forum member doesn't reply in a timely manner then I do my best to direct you to a resource. My response was a result on searching our knowledge base and not intending on selling you anything.
Following our conversation, User- kimzi supplied an answer, and along with your reply from the Xerox service representative it seems that it may not be able to do what you wish.
But In an effort to get a trained Xerox analyst's definitive response (and if you have a maintenance agreement,) you can call 1-800-821-2797 & ask to speak to an analyst.
They have a higher level of specific product experience and I would refer them to this forum topic by the following Copying-Faxing-Scanning/ColorQube-9302-Scan-to-home-without-authentication.
I sincerely hope you get an appropriate response
Fortunately unlike some other companies, Xerox has a group with the ability to create custom solutions to complement the common printer functionality and if it is not able to perform that function, then I would consider inquiring as to the cost of creating special programming to fit your needs.
Best regards,
