Default How stop annoying notifications that I already cleared on my phone

Is there a why to have it that when I clear notifications on my nexus 10, that those same notifications automatically get cleared on my LG G2 running CM 11. Or vice versa.

I am running into an annoying problem that when i setup reminders using google now, that reminder on my phone gets cleared, but the tablet i may not be near that the alarm for it can be quite annoying and wont' clear unless I manually go to clear it. Any help would be appreciated greatly !!!
