Stripe NodeJS create cutomer in multiple account

I use stripe-node, I have two account in my stripe dashboard with different secret and publishable key api. When I register my customer, i want to do this simultaneously in the both account, my customer will have to select the destination account (in a select drop down) to charge a new amount.

What is the best and simple workflow to do that ? Is it mandatory to use stripe Connect ?
