Account and Alternate Account Clearing (PeopleSoft FSCM 9.2 PUM 55, PeopleTools 8.62.12)

When coding the distribution line for transactions (vouchers, expense reports, purchase orders, etc.), we use both the Account and Alternate Account ChartFields. The Alternate Account field is automatically populated based on the Account value entered. If a user needs to change the Account, we have found that the Alternate Account value is cleared after the user tabs out of the Account field. If the user deletes or updates the Account value but does not tab out of the field, the Alternate Account value may remain populated, which can restrict the available Account prompt values and cause confusion.

Is there any delivered configuration, setting, or recommended approach that would improve the user experience in this scenario? We would like the Alternate Account field to clear immediately when the Account value is removed or changed, without requiring the user to tab out of the field.
