Order approval / rejection process

Hi,
I’m interested in buying the pro version of this plugin but I would like to confirm a couple of things please. What is the process for order approval / rejection? Is the order cancelled if it’s rejected by the parent account? We would like a sub account to create the order and then for it to be approved and paid for by a parent account. If rejected, we would then like the sub account to have the option to pay for it or cancel. Is this possible?

Also, can a sub account have the option of paying for an order unrelated to the parent account eg. for individual use. Would the sub account need a separate individual account for this?

Thank you.
