How to implement "Item Limit" for Summary Link Webpart?

Hello,

I would like to know how it is possible to do Item Limit (similar to Content Query Web Parts) for Summary Link Web Parts? Basically I want to limit the number of links they have there to a certain number, so it won't mess up with the styling of the page when users input too many items.

I've tried modifying the .WEBPART and inserting a <property name="ItemLimit" type="int">5</property>, from which I got from a CQWP webpart file. However, it seems SharePoint doesn't implement this as it seems to automatically remove the snippet when I insert it to the page.

Is there a way to implement Item Limit functionality for Summary Links Web Part? OOTB would be better.

Thanks!
