How to configure the Locator plugin's Locator fields sidebar tiddler to show text field instead of title?

In my usecase browsing by normal search, table of content, links etc. is not complex enough and the only solution I have found is to use unique titles (<<now “[UTC]YYYY0MM0DD0hh0mm0ssXXX”>>) for my tiddlers and search/create tiddlers by “field-combinations” using the Locator fields sidebar tiddler, but I need the above tiddler to display the text/content not the ID.

I know this can be done with the Locator View tiddler in settings by changing the Template of context items from link to transclusion but not with the Locator fields sidebar tiddler.

Any suggestions?
