Can you change Google Now activation word from Google to something else?

[cloud12077]

Just wondering if there is a way to change Google Now's activation word (Google) to something else, like change it to "Computer".

For example:
1. Turn on Google Now
2. Say "Computer.", "What time is it?"
3. Google Now reads what time it is.

Right now I can only do this:
1. Turn on Google Now
2. Say "Google.", "What time is it?"
3. Google Now reads what time it is.

Thanks!
