Unfortunately you can't, in the dashboard if you hover over the keyword
field a pop up says "An app published through the App Lab can only be
discovered through search when a user searches for its exact name."
Yes you can download them later, however is that the goal? Or is the
problem that these 3 asset files aren't being marked as required? As
soon as you make it required in the developer hub it should download the
asset files when you reinstall your app...
