Piping auth0-js webauth into @auth0/auth0-react universal login flow upon sign up

SDK: auth0-react 1.5.0 and auth0-js 9.19.0
Platform Version: React 17.0.2

Question about a signup/login flow. I want users to be able to signup outside of universal login using auth0-js (we have a lot of validations that need to be done against our signups) and then pipe that created user through our universal login flow. As it stands they need to sign up, then we have the universal login modal pop up to have them login, and then they can use the site. I’d like to remove this middle step and not need the universal login modal to pop up but still use the auth0-react library to maintain login state.

Is this possible?
