Deriving A Public Key From Base58

Hey Decred, I use bitcoinjs-lib for my bitcion projects... and when I want to derive a public key from a base58 key I would use the following code:

var hdNode = bitcoinjs.HDNode.fromBase58(derivedPubKey);
exports.deriveAddress = function(index) {
return hdNode.derive(index).keyPair.getAddress().toString();
};

Now, is this possible using decreds branch of bitcore? I cant find any functions for deriving a key from a Base58 key. Thanks a ton!
