Customize in-App notification for AP invoices

Hi All ,

We have a use case that whenever invoice distribution is coded to 200010 account, AP invoice should be autorejected. We made changes to BPM rule to acheive this. Is it possible to modify the in-app notification message which approver receives in his notification queue for autorejections and the custom reason stating that, invoice autorejected as distributions are coded to 200010 account.
