As a PM, I'd like to keep track of items sent to our Dev tool (in our case, JIRA) and I would like to have the ability to create a list report of items that exist in JIRA right now. If I had the ability to filter by JIRA URL, I could easily see where I need to focus my attention for other items not in JIRA, clear up our backlog not in JIRA, move items between integrations etc.
Note, it's not possible to create a custom field when trying this with an ADO integration.
Thank you for your idea. One option here would be to use a custom field. You could create a custom text field and map it to the Jira URL in your integration. Since custom fields are available to use as filters, you could then add this to a report to do the filtering that you need.
