I require assistance in automating the following scenario using AD Manager Plus. Is it possible, and if so, how can it be achieved? Can someone please guide me on this?

Upon a user's departure, we disable their account. After 3 days of ID disablement, we aim to remove the user from all Distribution Lists with names following the pattern "DST_xxxxxxx". The second task involves moving the user from their current Organizational Unit (OU) to the Disabled OU after 90 days of ID disablement.
