Importing & Linking Policies into SEPM with a script

Hi,

I need to make a powershell script that can take .dat policy files from media, import them into SEPM and link them to the correct groups they are supposed to be applied to.

I understand that this can be done quite easily in the SEPM GUI, but I need to make this anyways.

Right now, I'm not even sure if this is possible, so I would appreciate any help. Thanks!
