It's quite common to have a folder that gathers like actions, such as "Date Entry" and collect them there. Where you want to be careful is if there are other embedded actions in those, or it grows unwieldy as commonly a "To File" pile becomes. If you keep up with it regularly, it's just a recurring task. Not part of your Weekly Review.

I'd probably just capture an un-timed next action on my Calendar to remind me to do these.

Weekly Review is really power reviewing and planning time, not doing time.

Hope that helps!
