Extend lock screen timeout?

[funops]

Hi folks. I have a Nexus 7 1st gen tablet and it was updated to Android Lollipop yesterday. I like the feature whereby I can preview notifications at the lock screen before entering the unlock info. However, this screen timesout after about 8 seconds which doesn't give me much time to skim the notifications. I usually have a dozen or so because of new email. Is there any way to extend this time for the lock screen before I have to enter the unlock info?

Thank you,
