Different account for Lightroom and Sign

Hi all. I have a adobe subscription because of Lightroom - so i have a photography email. BUT I use adobe sign for business (which is not photography) - I don’t want my signature files go out with my (photography) email ie my main adobe sign on email. Can I use two different email? I don’t care about login - happy to use same - but I want sign (and document) to show a different email ie my business email when I send docs for signing. Thanks much.
