how to show custom 404 error page on deletion of any record for summary page

Hi All,

I have a requirement in which i am opening summary page in new tab, and from previous tab i have deleted that record through record action.

Now, when I am going on summary page tab of same record, and reloading the UI, It is showing error like 

"An Error has occurred.

Record does not exist, either deleted or don't have permission "

Please help me if there is any way i can replace this message with custom appian UI showing This URL does not exist and 404 - not found 

Thanks in Advance,
