Ability to check "Do not show this message again" for Task/Sub-Task Deletion Confirmation Message

When deleting a task, sub-task, or event in a Delivery Map by clicking the trash can icon, a confirmation message pops up to confirm if the user wants to make the deletion (see CC-Snip.PNG). It pops up every time. We are getting user feedback that they would like to make the overall Delivery Map customization process more streamlined with less clicks ("less cumbersome"). I am proposing we add a checkbox in the deletion confirmation message to "Do not show this message again" so that this popup doesn't keep impeding a user who is deleting multiple items in succession. This feature is implemented elsewhere in Concourse (seem CC_Snip2.PNG) so hopefully the technical implementation would not be too heavy.
