Bulk edit delivery times

Hi All. Is there a way that we can bulk edit delivery times (as I need to increase them) or do we have to go into each listing and change them manually one by one (I’m keeping my fingers crossed that they can be bulk edited)

Sadly I think the only thing you can edit in bulk is the postage rates not dispatch times.

Thanks @OrchardFelts I had a feeling that would be the answer : /
