options.Constrain.Count for getLinks()

[ko-redtruck]

I link all posts to an anchor of type tags with the text all. This way I can retrieve them later with: getLinks(anchor("tags","all"),"post").

Now let's say that I only want to get 5 out of my millions of posts on the platform (for performance reasons) or I only want to load a few posts dynamically on page scroll. To achieve this I would need to have the option to set a limit on how many entries I want to retrieve with getLinks(). To my knowledge this isn't implemented yet. Are there any other clever ways to solve this problem?
