global change tuplet appearance after the fact

[mscherperel]

I've decided, after entering several pages, that I want all the tuplets to have brackets. I've change the tuplet default appearance to "always use specified shape" in document options, but sadly it does not seem to work in arrears. Is there a way to change all the tuplets already entered other than doing to each of them one by one?

Select all, then use Utilities -> Change -> Tuplets.
