How to link my developer account to my company in order to test my company's paid features ?

Hello,

I first created a developer account with my work’s email, then i realized that i do not have access to the advanced signing methods that i have to test.

I have a user in my company’s production environment, but it shares the same logs with my developer account, that is not linked to the company, so when i log in the developer realm using my work email, i do not have access to the advanced features. 

Is there a way i could associate my developer account with my company ?

Thank you

Mathieu
