You're right. I don't know how to do what you want in Mathematica.
Anyone: Can it be done?

BTW, be aware that, even for a limit involving just one variable,
Mathematica will always assume a default direction unless, of course, you
have specified one yourself. For example, Limit[Floor[x], x->0] gives 0,
despite the fact that the ordinary (i.e., bidirectional) limit does not
exist.
