Contact who are in several departments of different accounts

Hello community!

Is there any way to assign multiple departments (in different accounts) to a single contact?

For example, I have a contact who works in several accounts and in each account he is in a specific department. Some contacts are in multiple departments in the same account. For rights, it's easy, we can use functional/organizational roles but I need my contact to be in multiple accounts. How can I do this? With Creatio, I can only assign one account to a contact. If I assign another account, the previous account will appear in the job experience and it will not be his primary job..

About the accounts it's something like that :

Main Entity

───unit

   └───sub unit 1

       ├───sub sub unit 1

       │   └───sub sub sub unit 1

       └───sub sub unit 2

           └───sub sub sub unit 2

I have up to 5 levels of depth (main -> unit -> sub unit -> sub sub unit -> sub sub sub unit).

And I need my contact to be in 2 different units (sub sub unit 1 and sub sub unit 2 for example).

Each (sub) unit is an account because I had too many problems with departments (departments don't appear for some reason but I am able to assign a department to a contact.

I need to see the same contact working in two different accounts. So, in the page of the first account, I need to see the contact. For the second account as well.
