Using the same user for "ai-llms" and "ai-personas" in ai!

In artificial intelligence tools (ai-llms), users are added to the created model. And users are added in “ai-personas”. Now, when I want both users to be the same, I cannot do this. If I delete one or merge it with the other, the other is deleted and the new user creation button appears.

The behavior I expect here is to cancel the user creation feature in the ai-llms field and make the user selection feature in the “ai-personas” field. Here, we should also be given the ability to select an existing user. In other words, we should be able to add an existing user to the model in the persons.

Administrators and moderators cannot be deleted, users created in the model section cannot be combined with users created in the persons section, or even if I could do this, I would not be able to achieve my goal because it would ask me to create a new user.
