A way to delete chats prior to certain dates

I think itd be cool to be able to delete chats prior to any date selected.

For example, I know I won’t ever access my chats from before April, so I’d like to be able to delete all chats from before April 1st. 

Could even have an option to delete chats within a selected range, ‘Delete all chats from January 5th to February 18th.’ 

or be able to ‘delete chats from last: 24 hours, 7 days, 30 days, 3 months’ etc.
