Question [Q] refreshing gnow cards on gwatch


i'm a gwatch owner since july, paired with an N5 phone with no problems at all (except some voice command not working sometimes, with a sad cloud icon). Yesterday there were some soccer matches here in Italy and i was driving, wanted to check out the partial scores straight on my wrist but the scores were not updated, since che gnow cards were not. so i had to take my phone and refreshing the gnow cards from there, then they went updated on the watch. Question: is there a way to refresh gnow cards from the watch? I think it would be very useful, maybe we can suggest it to google...
any advice?
