No, it will work with more than one as well, you just need to loop
twice over all the buttons and keep track of all those which should be
right-justified.

"Everything on this line" on which line?

Do you mean you want to display an entire screen line justified to the
right?  Then we already do something like that with R2L lines
(although there we also reorder display elements, something you don't
need here).
