Ncentral password policy script / task

Hi Guys, i just have a question my client has a few users (Workgroup) environment which consist of windows users and Mac users. He has requested if possible to setup a password policy for the users to change there passwords every 45 days windows and mac users. All the users have the pro license assigned in Ncrentral. My question is, is it possible to create a task / script in Ncentral to run a policy to make the user change there password after 45 days?  If not is there any other suggest to execute this request? Thank you in advanced.
