Regretably yes.

I just wanted to point out that it might be useful to implement such a
functionality for wxt (Timoth=E9e was a bit sceptic).

"bind a hotkey" is not equivalent to "have it in menu". I never came
to an idea of binding a hotkey.

This might be true, but usually printscreen is the only choice (unless
a specific program supports some kind of vector graphics). I doubt
that one can export any kind of vector graphic out of the windows
terminal, but I may be wrong.
