breaking line in gb4e [duplicate]

Question

I use gb4e for my linguistic examples. When the example is long, gb4e breaks it into two lines (of the first and second, glossing, lines). However, I sometimes want to break it at a certain point. How can I do that? (I can't find any method in the gb4e document.)

A MWE is as follows. I'd like to break the line after the first occurrence of the word 'Mink'. If I do it in the second way, unwanted spaces appear between the lines. (I'm using xelatex.)

\documentclass{article}
\usepackage{fontspec}
\usepackage{gb4e}

\begin{document}

\begin{exe}
\ex
\gll thu-mi-t-əm =k'wa Mink.  chichiya7-u-s =k'wa Mink te= c'estaya\\
go-RLT-CTR-PASS =QUOT Mink grandmother-PST-3POSS =QUOT Mink DET= knothole\\
\glt `Mink went towards it. The knothole was Mink's grandmother.'\\
\end{exe}

\begin{exe}
\ex
\gll thu-mi-t-əm =kʼwa Mink.\\
 go-RlL-CTR-PASS =QUOT Mink\\ 
\gll chichiya7-u-s =kʼwa Mink te= c'estaya\\
grandmother-PST-3POSS =QUOT Mink DET= knothole\\
\glt `Mink went towards it. The knothole was Mink's grandmother.'
\end{exe}
\end{document}

Answer 1

Try this:

\documentclass{article}
\usepackage{fontspec}
\usepackage{gb4e}

\def\Id#1{\vskip-.32cm\hskip.01cm\vtop{#1}}

\begin{document}

    \begin{exe}
        \ex
        \gll thu-mi-t-əm =kʼwa Mink.\\
        go-RlL-CTR-PASS =QUOT Mink\\
        \Id{%
        \gll chichiya7-u-s =kʼwa Mink te= c'estaya\\
        grandmother-PST-3POSS =QUOT Mink DET= knothole\\
        \glt `Mink went towards it. The knothole was Mink's grandmother.'%
         }  
      \end{exe}

\end{document}

The macro \Id changes the placement of the text using a vtop box, which overrides the gb4e package placement of that text.
