Supporting Windows

We have a K1000 virtual appliance in our main location.  We have many remote locations that connect over T1 lines.  When Kace pushes out any update or does an inventory, it floods the T1 lines with so much traffic that it grinds the network at the remote locations to a halt.  Is it possible to set up the K1000 in a way that it pushes out all updates and software patches to a local file server and then have the remote PC's pull the updates from the server instead of the K1000?  I realize the best solution would be to have the updates run overnight, but we have a few locations that are open 24/7 and some people still shut their PC off before they leave.
