[FieldTrip] How do you prevent ft_resample from filtering your trigger channels?

It seems that ft_resample applies to all of the channels in the data
structure. During resampling fieldtrip applies a filter, which adds
artifacts to the step function in the trigger channels. For
downsampling at least it would be great if you could specify a subset
of channels to be downsampled by simple decimation (i.e. skip the
lowpass filter). Is there any built-in way to do this?
