Changing all expiration date for users in a group

[Rick_Rodrix]

Hello everybody!
I´m not using at this time LDAP groups to authenticate users, so I´m using "Check Point Password".

Does anyone know if there´s a way to do a massive modification for the expiration date for only one user group?

I´ve found the solution below, but the command "fwm expdate" has a lack of options.

How to perform a mass modification to all user accounts' expiration dates 

There´s no options for groups, you can only change all accounts date expiration.

Thanks in advance.
