Why in the tab “Interaction” > “Download file” there is no possibility to download two or more different files. Is it possible to download only one file for the entire site, without the possibility of replacing it at all?

If you add to the Asset Manager different files (zip, pdf files), the dropdown for download file will display all that were added to Asset Manager for you to select. Blocs also has another feature that will create a button on the canvas when add files directly on the canvas near an object.
