copy User preferences to Groups

Hi

Using SDK,

we can get,set and add new preferences in a user's profile.

Here is the link below which explains that.

My question here is instead of setting/copying preferences from a user to user.

If it's possible to set/copy for a complete/specific user groups.

Let take an example:

Group A

Group B

Group C

Group D

I want to set/copy preferences from a user to ONLY Group A & B. please advice. If possible share some code that really helps me.
