Change Manager approval rule based on manager type

Content (required):

Hi - we currently have our Change Manager approval rule configured to send FYI notifications to both the current and proposed managers when the transaction is approved.

We also have a matrix manager type called Project Manager.

Our current setup is sending FYI notifications when either the Line manager or Project manager is changed. However, we would like notifications to be sent only when the Line manager is changed.

Is there any way to configure this ?

Thanks
