Solidity: Saving arbitrary data into bytes array and later parsing it

I want to create a function that receives two addresses and saves them into a bytes array.
later a matching function will receive this bytes array and parse the two addresses.
function addressesToBytes(address add1, address add2) public view returns(bytes combined) {
    combined = new bytes(40); //since each address is 20 bytes
    //store the two addresses in the bytes array
}

function bytesToAddresses(bytes combined) returnes(address add1, address add2) {
     // here set add1 and add2 values from combined bytes array
}

I saw this answer. but it was not enough :(.

This will get the job done:

    function encode(address _address1, address _address2) public pure returns (bytes memory output) {
        return abi.encodePacked(_address1, _address2);

These functions are also pretty efficient. The encoding function takes around 900 gas for execution and the decoding function only around 670.
