Open Source Document Management System | OpenKM

Everytime I perform a search, I want to add some files from search results into a place e.g. shopping cart.
Later, I will go to the shopping cart to download all the files as a zip.
Is this use case possible in OpenKM? Thanks.

This should be a customization, is not the first time somebody asking for it. Really openkm is a repository with documents and you are selling access to this documents. Here might be applied several logics for accessing to the documents, that's why does not exist a singular development and it is a customization ( for example, might be a single download or download available during a period of time etc.. )
