RSS feed title customization for specific tags?

I use the below code for putting a unicode arrow after a title on the archives page for linkposts. Is it possible to add a similar customization to the feed.rss template so that the title would get the arrow in RSS reader apps? I want folks consuming the RSS feed to know there's a linked post to go read beyond my comments. I also have a YAML value for linkpost, if that somehow works better for this use case than the tag value.

{{#allEntries}}
       <div class="row">
            <div class="column left">          		
                  <a href="{{{url}}}">{{title}}
                      {{#tagged.linkpost}}
          			&#x21FE;
          			{{/tagged.linkpost}}
                  </a>
            </div>
              <div class="column right">
                  <span class="smalldate">{{date}}</span>
            </div>
        </div>
        {{/allEntries}}
