Schedule Time for GUP to get content from SEPM

Hello everyone,

We are using GUP's in a few of our slow link offices (1.5 meg pipes). they are working pretty good however we want to find a way to "schedule" when the GUP gets updates from the SEPM, even one computer copying a definition update over our slow wan links is too much. we want to tell our GUPs not to update until after hours.

Does anyone know of a way to achieve this? I know its not a setting at least not one that Ive found but maybe a scheduled task to kill a service?

Any thoughts would be great!

Thanks!
