Limit age of items in Notification Center

Hello,

Is there a way to limit the age of items in the Notification Center? I have 20+ items in the Center because it seems to be retaining messages up to a week old.

My Lezyne Super GPS bicycle computer will download notifications and display them while I am riding, which is a useful feature. But when I pair the unit with my iPhone at the beginning on a ride, it downloads all notifications in the Center. This can impair access to the unit's features when I need them.

I asked Lezyne Support if I can set up the unit to only import new messages that arrive after I turn on the unit. Reply: "We don't have the setting to only provide new notifications, based on the way iOS shares notifications to outside apps."

Any solution to this problem?

Thanks.

Matt
