Texmaker - autocomplete problem

Is there a way to stop Texmaker from auto-putting the completion tag of every command when I use autocomplete? Like \begin{document} and I press enter in the auto-complete and it includes the \end{document}. Is there a way to switch this off without switching off auto-complete?

for what it's worth: former versions of texmaker used to put only the \begin-tags with auto-complete (or the \end-tag, where applicable) –  long tom May 31 '13 at 18:30
@longtom yeah, that totally makes sense. It should've been like that. Could you tell me which version? –  SPRajagopal May 31 '13 at 20:38
i think that was somewhere around version 2.0... (that's way back) –  long tom May 31 '13 at 21:18

I think that is not possible without touching the source code. You can customize completions in in User > Customize Completion as explained in Customize auto-completion in Texmaker. However even any custom completion with \begin{...} is ended automatically with \end{...} and very unfortunately you cannot modify the items provided by TeXmaker.
I figured that a modification of the file settings could do to the trick, but I failed completely in this sense. As explained in Backup of user-defined entries of autocompletion in Texmaker? you can save a setting file, modify the fields of Editor\UserCompletion or Shortcuts\data where the are defined shorcuts as \\begin{quote}\n/\n\\end{quote}/0/1 and restore it, but this has no effect on the default autocompletion, as well as modifying directly the hidden configuration file ~\.config/xm1/texmaker.ini ... so this a dead end for me. :-(
