Sure, here are two scenarios: 1- Connected to YakiHonne using any method (an extension, an nsec ...etc) and adding both wallets via NWC (in this case you're connected with one account but having multiple wallets in which you can switch seamlessly upon payment) 2- Connected to YakiHonne using an extension and adding both wallets to your extension (in this case to achieve your purpose, both wallets in the extension should point to the same account, meaning you have to add the same nsec to both wallets so it can count as one account)
