No, it cannot be done properly for everybody:

grep foo bar.txt | tee output.txt

Unfortunately, this corresponds exactly to portage's setup:
Commands like einfo would have to produce different output
on different channels which they cannot do if portage
redirects/copies globally. Portage would need a rather
cumbersome (and presumably slow) catching of such output
for each command separately.
Filtering the logfiles afterwards is probably simpler.
