Map users when importing from Gitlab

Hello there!

When importing a project from a Gitlab, users from the commits and MR got a different email/author name and Gitlab username there than on the Gitea (destination). For example, firstnamelastname user on Gitlab used his personal email, while on Gitea, I’m using LDAP with a username firstname.lastname (note the dot) and also identify him via his corporate email. So there’s no way Gitea make the association automatically.

Is there a way to manually map those imported “imported Gitlab user” to their local valid LDAP user?
