Title on Custom post is a must?

I have created a Field Group “Insect” with + 10 custom fields
I have created a Custom Post Type “Insect”
I have connected Field Group to “Settings/Location/Post types” = “Insect”
I have unticked the Custom Post Type “Supports” (selection to the right) so it only supports “Revisions”

I would like NOT to use post “Title”
Alternatively, I would like to use one of my custom fields as “Title” instead.

Reason is I want users to register Insects (and since these do not have unique names like “John” or “Claire” it does not make sense to have a field called “Title”) – Seems WP requires “Title” to be filled in.

Is there a solution/alternative?

Thnx!
