Help with mafia script

Hello, I am trying to create mafias for my FiveM server, the best way I found to do it is to duplicate the esx_policejob and rename everything, however my idea for the server is that users can belong to a mafia without having to change current job, for example, being able to be a police officer while belonging to a mafia. Could police work be modified in such a way that it can achieve this or is there a script that already does this on its own?
