This could be done by a module (added to each page) or a skin object. I am not sure, but it should be possible to use 2sxc or Open Content to get this.
Also DNNSharp offers something like this, read Page View Count | DNN Sharp Documentation Center please.
Anyway: feature requests can be done here: Issues · dnnsoftware/Dnn.Platform (github.com) - but please be a little bit more polite than writing "Need to!" in bold letters...
