How to Create "Import Id" field type

[Matt Wilson]

Is the only way to create a field with an issue type of "Import Id" to do a CSV import?

I'm consolidating Jira projects onto one server (via the project import method), and one of my boxes has this field type.  I'm assuming it was from a Bugzilla to Jira import many years ago.

The above isn't a terrible workaround, but just wondering if I'm missing a simpler alternative...

Cheers
