Allow editing of text macros after creation OR support dead keys

I have been very happy with Qt Creator for a long time now, but there is something I really miss. Currently, I am using Qt Creator 4.6.2 on Linux Ubuntu 18.04.

Problem: I can record/save/rename and assign keyboard shortcuts to text editing macros. However, I would like to be able to edit a macro once it has been saved.

The current problem I have is that I am using Doxygen to document C++ code in two languages (English and German) and need to define the switches for English and German like this:

\~english \~german

I am using a laptop with a Swiss keyboard, and the tilde character "~" is only available as a dead key. Unfortunately, the macro recording facility does not record any characters entered as dead keys. So I have to write, for example:

\$english

and do a global search/replace for that sequence later on.

What I am missing is either the capability of editing a macro once it has been saved, or else enhance the recording facility to record characters entered with dead keys. I found the ".mac" files under "~/.config/QtProject", but cannot hack the binary format used.

Thanks!
