A new feature was rolled out recently that automatically announced speed limit changes if the difference in limits was significant. However, I have come across many cases where there's a fast speed limit change that occurs under the announcement threshold, or in cases where announcing the speed limit change would be unnecessary (i.e. turning onto a new street). Similar to how turn instructions are given a dropdown with "waze default," there should be an option to select whether or not a speed limit change is announced on a route. These options should be under the same set of menus for a turn, similar to turn instructions, restrictions, turn enabled, difficult turn, and turn closures.

Options being:
"Waze Default" (announces if drop is above mph threshold, which is currently the automatic standard)
"On" (announces any speed limit drop, greyed out if the next segment has no speed limit change)
"Off" (does not announce speed limit change)
