Can I get the wallet in bitcoind to use P2SH segwit (on testnet)?

Can I use the wallet functionality in bitcoin cli daemon with P2SH segwit on testnet/regtest? Meaning, can I receive on these addresses and send from them?

And if I can, how?

I cannot find it anywhere in the help. The only one that gets close is addwitnessaddress, but that does something else, too.
