Create multiple accounts in reddcoin core

I have downloaded the reddcoin core application and want to buy reddcoin. Now my family wants to join the community and I should manage there accounts on my laptop. Who do i create an account on one laptop for multiple users each.

I can create as many addresses to recieve or send rdd coins but the transaction is just executed for one wallet. Is there a way to manage multiple wallets? Maybe via the commandline tools?!

Thank you for your help.
