Make elision a customizable shortcut

Your idea

The elision symbol is a symbol that happens in lyrics. Although it is not so common in English, it is in other languages, and for that it has its own assigned shortcut.
In Musescore, the shortcut was first introduced for v3 in #6928 (Ctrl + Alt + _) and has recently made to work again in MU4 in #19018.

As there has been a reworking of the shortcuts for mu4, maybe it would be better to include it with the other shortcuts, to allow the user to change it? Or perhaps, should it follow the behavior of other apps (explained below)

Problem to be solved

This idea would improve the discoverability of the shortcut and allow for its customization, and improve the cohesion of all shortcuts.

Prior art

Both Sibelius and Dorico automatically replace the underscore (_) by the elision (U+E551 in Smufl) when the symbol is entered in lyrics mode.
