The functionality you would require is similar to that for subscriptions/recurring payments - which was abandoned by X-Cart because of the PCI adherence complications of the methods they were using to store credit card information.

The closest thing you will see here is probably customizations that BSCE has done using BrainTree Transparent Redirect and implementing the vault feature. (See this thread.) You may want to talk with them about what it would take to do the customization you describe. It is likely only worth the development cost if you have high volumes, but they could give you a better idea.
