You are being facetious. Libraries used to be able to do this and this is exactly how it was working until relatively recently (I received a notification earlier this year as someone who submitted requests for digital books in the past).

> If its not in the catalog requesting it from the library isn't really doing anything for you but give you false hope of it appearing.

That's precisely the point. If it's not in the catalog, there has to be a way to request it to be added (assuming the publisher allows that), but right now there is no even a mechanism to do this, as there is no competition and the full control is on the Libby side to include or not include an item (without libraries having any say in it).
