You can use this custom alias for a while:
Code:
alias mfilter {
  var %a = $1,%b = $+(/,$chr(40),[,$remove(*?&,$3),],$chr(41),/g),%c = $2
  %c = $regsubex(%c,%b,$replace(\1,&,\S+,*,.*,?,.))
  %c = $regsubex(%c,$+(/,$chr(40),[,$3,],$chr(41),/g),\\1)
  tokenize 32 %a
  !filter $+(-,$iif($prop = c,c),$iif($left($1,1) = @,w,f),$iif($left($2,1) = @,w,f),g) $1 $2 %c
}

$mfilter(input output,matchtext,wildmatches)[.c]

Example: //noop $mfilter(@@ @@,& & hello? & &,?).c
This will filter yes yo hello? you there
use the .c property to clear the output.
