Generate skey from different addresses from the wallet?

I was able to generate the keys needed for CLI with my Daedalus wallet. I can only do transactions though using the address generated by the steps at Create a signing key from an address in Daedalus wallet (Resolved) - #4 by Vaders. My question is how do it when using a different address from the same daedalus wallet? Or how do i create the skey for a different address (same wallet)?
