Front Page Port Errors - Prevent For Some Interface Types

We've just started monitoring a bunch of new wireless access points. Observium correctly picks up their apr0 and apr1 interfaces, with an ifType of "ieee80211", i.e. the wireless radios.

On the Observium overview page/dashboard, it's started flagging up all of the apr* interfaces as having errors. While this is correct, it's not very useful because a wireless interface is almost always going to have some low level of interface errors. 

Is there a way to ignore these interfaces for alerting in bulk?

I can modify the device ports page for each device, but that's a slow process for a large number of devices. If no such facility exist, please improve the alerting or dashboard. One idea I've considered is having an "ignore interface type X for port errors on the dashboard" config option, or "ignore alerts for all ports of type X" option.
