Moving Tasks items in bulk to another Due Date

I think I’ve been a bit too optimistic about what I can still achieve before my Holiday starts and now I have quite a few Tasks which are due for the end of the week which I won’t be able to finish.

Luckily, they were not critical for me to keep me from going on my Holiday anyway.

Is there any way to move all these tasks at once to a date one week after my return?
