Is there a way of creating an short alphanumeric id to associate with a workflow instead GUID or ID

Hi mcooperDART,

May you want to check out folio. 

 folio is to distinguish one workflow instance from another. The folio is often a unique value, but it does not have to be unique, nor is it required.

You can refer to the link below for further details:

Should you feel that this post is of use and or an accurate solution to the raised question, I kindly encourage you to mark it as such using the 'Mark as Solution', 'Kudo' andor ‘Me Too’ options.

Best Regards,

Kate
