Actually, there is a way around this in P99SEsp6. Create a DRC rule that specifically states that the clearance between any two objects of the footprint <company logo> is 0 mil. Next, also create a DRC rule that says the minimum track width of the footprint <company logo> is 1 mil and you're all done.
