To better support payment workflows, especially with PayPal, it would be highly beneficial to separate two currently combined behaviors:

At the moment, the option “Allow payment method change after checkout” also controls whether customers can retry a previously aborted payment (e.g., PayPal popup was closed by mistake).
However, enabling this option on PayPal unintentionally allows customers to change from any other payment method (e.g., Prepayment/Bank Transfer) to PayPal after the order is placed. This causes serious issues in ERP/WMS integrations where such changes are not allowed.

Proposed improvement:
Introduce two independent configuration options per payment method:

“Allow switching to this payment method after checkout”

“Allow retrying an aborted payment for this payment method”

Benefits:

Customers can still complete PayPal payments if they accidentally aborted the payment window.

Merchants can prevent unwanted payment method changes (e.g., Prepayment → PayPal) that break ERP workflows.

Provides clearer, more predictable, and more granular control over payment behavior.

This enhancement would significantly improve flexibility and avoid unintended side effects in multi-payment setups.
