I saw an update that leads me to believe we can mass update now.  However the instructions reference "edit" and that is not an option.  I only have "create"

It won't let me post a link for the instructions so I went to quickbooks support
and  searched for

Add and edit multiple customers, vendors, and items

(I'm going to try the link without the hyperlink below)
