Bulk editing delivery times

I have looked through the previous queries about bulk editing and wonder whether anything has changed regarding bulk editing postage times. Rather than close my shop for a few days I would prefer to adjust the times and I am always looking for quicker ways to do things! Does anyone know?

No there isn’t an update.

Thank you for letting me know.

This is the one thing I’d really like to have - would be so useful to change the number of days on everything, especially at busy times! @Folksyadmin
