How can I change the way Mathematica orders exponents?

How can I change the ascending order that Mathematica has of ordering the exponents, to a descending one.

For example, get

In [1]: = s ^ 2 + s + 2
Out [1] = s ^ 2 + s + 2

and not the traditional

In [1]: = s ^ 2 + s + 2
Out [1] = 2 + s + s ^ 2

s^2 + s + 2 // TraditionalForm? See https://mathematica.stackexchange.com/questions/33130/why-does-mathematica-order-polynomial-forms-in-reverse-from-traditional-order -- See also https://mathematica.stackexchange.com/questions/9570/how-do-i-reassign-canonical-ordering-of-symbols – Michael E2 Sep 25 '21 at 03:34
Yes but always, without having to add the // TraditionalForm – Guillermo Rojas Sep 25 '21 at 03:37
Plus is Orderless, so the ordering is canonical. You'll have to do something special, if not TraditionalForm then something else... – Michael E2 Sep 25 '21 at 03:38
One can use e.g. PolynomialForm[s^2 + s + 2, TraditionalOrder -> True], see e.g. How to keep Collect result in order? – Artes Sep 25 '21 at 03:39

Are you just concerned about output formatting? If so, you could modify $Post, which is a user-definable function applied to every output expression. – thorimur Sep 25 '21 at 03:41
@thorimur, yeah thats what I want, thxs – Guillermo Rojas Sep 25 '21 at 04:00
