Currently, entities in the user input dropdown list are identified by a single, default field, which may not always be meaningful to users. For example, GitLab groups and repositories are identified by an integer ID, which doesn’t convey much information. From a user perspective, a more relevant identifier would be the full path (e.g., group/subgroup/repo).

In other cases, users may want to see different properties or even a combination of properties to make more informed selections. We need the flexibility to configure which fields are exposed for each entity's list entry in the user input's dropdown list.
