Shopify Plus Checkout - Can we force default payment method, to be checked until user changes it?

Hey,

We have different payment methods for companies and for physical person. We decide that on information step in checkout. And when user decide to purchase as a company, and go trough all steps but not make purchase. Then go back to information step, change to make a purchase as a physical person, then skip 2 steps and go to purchase, get payment method for company. For now we can not refresh all steps, when user change information step. And my question is can we somehow in code force default payment method, to be checked until user changes it? I will also live here one bubble for better understanding. https://app.usebubbles.com/dvNuzYWPgY2zepP4a5pjkJ/test

Thanks in advance,
