'Select All' in templates/sequences to mass delete

Because we can't add personalized photos as a token, we create new sequences for each contact/prospect. we create a duplicate of a general sequence and add a personalized photo for each lead. Which means we have  A LOT of sequences and templates created everyday. Now that there is a limit of how many we can have in our account, we need to delete our templates and sequences frequently and we have to "click" every one which means it takes forever to get through it. 

90%  of our time doing this would be saved if there was a select all option, see image. Can you please add a select all option/checkbox?
