Unfortunately, you can't enter too many locations: Google only offers transit planning for the city of Portland, but they plan to expand to cities in the US and around the world.
Try, for example:
100 nw couch st, portland to hillsboro, oregon by 8pm
pdx to portland, oregon at 7pm
pdx to 100 nw couch st, portland, oregon
