'On Hold' for a folder of projects
 

Here is my problem:

I'm on vacation this week.
What I most need is to my head away from my work.

Since I have separate top level 'Work' and 'Personal' folders, the way I've handled this on OmniFocus for Mac is to 'Focus' on the 'Personal' folder (I'm very open to a better way).

But there is no 'Focus' feature that I can find on OmniFocus for the iPhone, so I can't figure out how to exclude *all* of the projects in my Work folder (which is nested several levels deep) from my Contexts on my iPhone.

Any suggestions as to how to do this on the iPhone (or a better way to approach the problem on OmniFocus for Mac)?
