On the Review Actions screen, you can use the functions under the tab labels, left of the filter buttons. From left to right, you can Reprocess, Postpone Actions Date (my favourite as I have the same problem as you), Change Context, Change topic, Change Criteria, Change Status, Change Project, Set to Done (I wish I can select all actions on my today tab - ctrl+A by the way, and press that button more often), then Delete on more than one action in a few clicks.
So for my daily review, I go to my Overdue Tab, select all actions left and postpone them by a few days...
To select actions, you can also use the shift if they are consecutive or the ctrl key if you want to be picky.
I use these buttons a lot.
