[Koha] Local administrators for library consortium

[Sami M. Rasheed]

Hi,
We have migrated to Koha 23.05, and now we have 38 libraries (a library consortium). Every five libraries should have a local administrator. We plan to grant permissions to some users to grant access to all areas to manage five libraries together. Unfortunately, Koha doesn't allow users to connect to library groups; it only has a rule to connect users to one library.
How can we resolve this issue?
Thanks
