I'm using "acmart" as the template. We have three authors, all from the same university but one of the authors also affiliated with an institute. I'm aware of this question, however, its compiled version generates affiliation/email blocks redundantly.
My current version is like this:
\author{Naghi Mamuli$^*$,\hspace{1em} Arastoo Amel$^{*\mathsection}$,\hspace{1em} Homa Saadat$^*$ }
\affiliation{%
\vspace{-1em}\institution{Aliabad State University$^*$ \hspace{0.3em} North Laboratory$^\mathsection$}
}
\affiliation{%
\institution{\{naghi,\hspace{0.2em}arastoo,\hspace{0.2em}homa\}@aliabad.ac.ir}
}
That is compiled as:
As you can see, each of authors, affiliations, emails gets only one single line.
This is fine until we want to add ACM Reference Format:
As you can see, the marks (e.g *) that I have used to associate affiliations, now are visible in the "ACM Reference Format" since it is created automatically from the author names.
Is there any way that I can use "marks" but remove them in "ACM Reference Format"? or change this code to compile concisely like this one but without any problem in "ACM Reference Format"?
