Add a section with payment informations

Hello,

Our clients are ordering expensive services so we don’t let them pay through Stripe or Paypal for example, as it would cost too much in fees for the small service they provide.

Would it be possible to add a section below the table, where we could provide payment informations to our clients? → https://i.imgur.com/Qw13ggq.jpg

I could ask my developer, of course, but as you know, it would be overwritten at next plugin’s update.

Thanks in advance for your help.

Best regards,
Fabien.
