I mean, to some degree, that's what the US has historically done and can do, as a consequence of being the world trade (and therefore reserve) currency. A side effect of that position is decreased sensitivity (aka inflation) of that currency to money printing. Because you're effectively amortizing each new dollar's dilution of value against {everything the US uses dollars for} + {everything the world uses dollars for}. Which is a much larger denominator than national-only currencies. (And side note that being a trade currency is somewhat of a Faustian bargain, because it carries an expectation/obligation that you will create sufficient amounts of your currency to facilitate international trade) If the US keeps using the dollar as a fast pass to imposing unilateral sanctions internationally, and de-dollarization expands, there will be a very different level of correlation between monetary policy and dollar inflation.
