How to default Natural account from Employee default account for corporate card expenses

Our customer is having multiple Card Programs where cards are given to individual employees and the card program is company paid.

Our requirement is for one of the Card Programs, to default Natural account on the Expenses from the default expense account assigned at the Employee HR profile. When expenses are imported using credit card transactions file, we wanted all the expenses to default natural account from default expense account of the Employee HR profile.

Is there any solution or workaround to achieve this?
