Yes but not if the short tests work reliably. The best not yet on the market short tests we have do have a lot sensitivity but high specificity, i.e if they say you have it you most likely have it but if they say you don't have it you can't rely on it at all. (As as I know) This is still somewhat useful as it turns out they still do a reasonable good job wrt. Sensitivity iff you are highly infectious. So it might be useful to at least "weed out" the most infectious people before grant events or e.g. school, which would probably already be a great improvement I guess.
