Showing different fields as IDs in the upstream/downstream list

Juande Santander-Vela

Because we are importing a lot of existing system and subsystem requirements that had their own requirement IDs, we have a custom field that we are calling ALMA_ID (could be called something like Legacy_ID to better convey the general meaning).

Would it be possible to show this ALMA_ID field, or any other custom field? 

From the image above, it seems that only a few fields can be selected. It would be useful to be able to configure which field(s) appear on that list from the custom fields, or to have a particular kind of field that would be able to appear hear, to ensure unicity - although sometimes those fields could be empty.

Is that something possible? I guess we are not the only ones having legacy IDs that people want to refer to…
