Holidays and Vacation input through front-end

Hi,

It seems, after searchign in manuals and forums, there is no ability to allow inputing holidays or vacation days through the BoS app, the only way to input holidays and vacations is through the BOS Configurator. 

Is this right_ If so this is weird, not allowing to input a BOS client update its vacations or bank holidays through the front end - or even through an API accessing the typical government site that gives you details of bank holidays.

Has anyone done the above? It feels quite basic
