is it allowed to reverse angular component selector prefix to be a suffix?

Question

I have an angular app with a custom prefix for example myApp that generates the components selectors in this way <myApp-nav></myApp-nav>. for some reasons i need it to be <nav-myApp></nav-myApp> . another way cant go with it to add special characters to be <$-nav></$-nav> or <$myApp-nav></$myApp-nav> . i got Selector ($myApp-nav) is invalid.
