Add a user statement to automation for notification

Hi,
We want to be able to configure notifications to be sent out via automation to changes to items but not have these not be sent if a specific user makes the change. This way the owner of the board can be notified of changes made by anyone else. Currently they get notified of all changes even ones they’ve made themselves which leads to an avalanche of notifications when not necessary. For example:

Went status changes to anything send notification to user A if change made by not user A.

Thanks
