EasySync: Any Way To Sync Found Set?

GZync does this is there a way to do this within FM Easy Sync?
Perhaps I am missing the obvious.

"Folks use this to deliver just one user’s records–usually very specific things like “my customer visits for today” or “my active orders in this territory”.…
To control which records are pulled down to your iPads and iPhones: GoZync will look within the results of a find request for records that have changed since the last sync. If you can write a find request, you can sync that found set down to your users."

In the application I am working on it would be useful to just pull data for a specific region, since a full sync of the database may get too big over time, depending of course how full people keep their iPads.

Any Suggestions are most welcome,
Thank you

You can easily exclude records from synching by setting "ES_Exclude" to 1.

also look into the $$additional_pull_info calc in the EasySync settings script.
