Campaigns deactivated Timestamp

In this reference link: https://docs.marketo.com/display/public/DOCS/Automatic+Trigger+Campaign+Cleanup, I have seen the sentence “These idle trigger Campaigns will be deactivated on dd-mm-yyyy DateTime” with reasons… so as per my understanding there is a log maintaining in Marketo for identify the campaign deactivated timestamp. so why can't we use in Marketo visual page? I think this will be useful right?
