Easy enough to do, especially with Amethyst... I have 4 total accounts with their own nsec keys. I toggle all day depending on what I'm doing.
2 of mine are mostly for business nostr:npub1d9t8g0ahhqh554pzwatdq4q2jlqhmzx2e6vtjp9ay620ggf2cjus2whnfc and nostr:npub1llv0f7yfsk9fx4kr87ndjqz9flwmetx3zcg3r997y299qvhu3ecqncdqsm I use for advertising /zapvertising... I see a note that fits, I'll copy the note ID, hope over to the other account then zapvertise them. Easy peasy.
The 3rd account is my private one/anon account.
