How to Bypass Hotspot Usage Counters for local network

Hi

I have a network which my clients connect by hotspot. all users have time and also traffic limitation for access Internet. also they share files between each other.
the problem is when they have local traffic (not to the Internet) for example file sharng , the hotspot user counter increase !!!
while I want they have NO limitation in their local traffic , and just be limited for internet usage as I defined in their user limitation .
HOW I CAN BYPASS LOCAL TRAFFIC FROM USER HOTSPOT COUNTER ???

I read at this post "http://forum.mikrotik.com/t/how-to-bypass-hotspot-usage-counters-for-specific-subnets/49945/1 that their is no way. but in another post someone else told me that he solved this problem by contacting mikrotik. so I’m sure their is a way for this . please help me with any IDEA…
