Modify display machine count

In version 6.6 once over a 1000 machines are listed the message pops at the top of the access section saying 'limited to 1000, click to show all'

It would be great if we could choose a number less then a 1000 to display by default. Our techs all use the search function so we could shrink this to 300 displayed which could improve the speed of the portal.
