I also have this same question Peter, and I hope you can find an answer.
Pretty much in the exact same boat where we want to make a better portal experience for the end users as we've migrated to Employee Center and then also how we can track their progress through the pages and how many requests or INC submissions are being generated via various channels.
Almost popping this up here as a bump because I'm about to start adding a lot of offerings to our existing Services for Catalog submissions and want to start being able to link all impacted services and applications throughout the ITSM lifecycle, especially for Enhancement Requests and Support INC that may generate a release or change. I think some definitive help on this from those who have succeeded in this endeavor would be very useful to other admins and devs
