Change Storage Dir

I'm internalizing on pgAdmin4 installed by python wheels on Ubuntu and making some customization on it.

We run it in Server Mode and, we had created one email user to each DBA and one user for all the operators. For example, Jhon Snow got the email jhon.snow@pgadmin.com and he is a DBA. Maria Snow is Operator and his username to login to pgadmin is operators@pgadmin.com. All DBAs and Operatos had their own user on the Server, so they can login.

Basically we need to setup a new storage directory, only to save backups. I was investigating and the storage directory is under Data directory, but in our case, it is not an option, because the data dir is under root directory.

Is it possible to set, a different directory to storage backups shared to all system users? For example DATA_DIR should be still under root, but the backups, must be saved under /home/backups/.

Is it possible? Also for a future improvements, we want to separate operator's backup of DBAs' backups. Ex: operators' backups: /home/backups/operators/ dbas' backups: /home/backups/dba/

If something is not clear, please let me know. I'm able to modify python code.

Thanks
