We would love it if Publisher could import data from a file and load it into fields throughout a template document. I know Photo does fields, and Publisher appears to do some pre-defined fields. If we could define custom fields and then populate them with data imported from a file … tab-delimited, csv, json, xml, whatever … that would clear our way to migrating to Publisher completely.
+1. Only on day two of using AD full-time instead of Illustrator, and this is the first tool I've really missed, needing to change the appearance of dozens of tiny paths. Development of this feature has my full support!
