Can I save a wallet address I send to often?

Yes. In settings, you can save an external wallet address and give it a name. The next time you send, tap Pay, choose Phone number, and you'll find it under Saved addresses — no copying or retyping, which is where most address mistakes happen. The usual rules still apply: external transfers move on the Celo network, and only send to wallets you personally control.

But be cautious when saving crypto exchange deposit addresses (ie Coinbase, Kraken, etc). Exchances sometimes refresh/update your deposit address. Always double check direct to wallet transfers before approving.
