I use
\usepackage[style=authoryear-ibid, maxnames=1, maxbibnames=6, minbibnames=6, backend=biber]{biblatex}
\addbibresource{references.bib}
\DeclareNameAlias{sortname}{last-first}
to format my references. This will display it as follows:

Now I would like the last reference (TRCRC (2015b)) to be displayed as such and not just a dash -- (2015b). I found similar questions but many people ask how to write a dash instead of the author, I would like to do the opposite.
