We use the Jira Connector extensively and find it very useful in enhancing our productivity. One of the limitations we constantly run into it the inability to sync a field that does not exist in all Jira projects returned by our query. For example, we have a Top Level Project in Jira that we use for the highest level of deliverable. A ticket from this project is often broken down into Epics from multiple other projects. We have a field called "Target Sprint" in the top level project but it does not exist in the Epics from other projects. This is a key field that we can sync when we are only looking at the top level project. There are many cases where we want to sync the top level and the breakdown of epics. This prevents us from syncing the Target Sprint field for the top level.
The request is that when we do a sync from multiple Jira projects, It would be very useful to sync fields that only exist in some (or even only one) of the projects.
