[tracker2] blocking way points from showing up

[Ron K7CDL]

i have a OT2m ordered. what i want to know is there anyway to have a waypoint 
showing up by call sign? the reason why i ask is there is a few call signs in 
my area that i dont want to show up on my gps because they have 3-4 digis and 
its so crazy to have that many show up on my Nuvi 350. is there any settings in 
the firmware to block these call signs from showing up or is there any plans on 
adding this type of settings?
thanks,
K7CDL
