Title: [ADD] create_from_ui inheritable to add more fields on order and payment

Right now create_from_ui is static, so noone can add more fields here. If someone wants to inherit the POS module they need to override the entire create_from_ui. This intends to avoid that and inherit only which fields are going to be created.
