You can now create new ETH accounts in your Lumi Wallet. Each ETH account will have a different ETH address. You can give custom names to each account to distinguish the address. This feature can be used to divide the cash flows. Each separate ETH account can store tokens as well. 

To add another ETH account go to the Wallets tab, tap on +Add wallets, pick ETH and tap on +Add new account and put in the name.
