Custom Filename on Exporter to export to "portable HTML"

Hello, I created a custom exporter to export the filtered tiddlers into a new ‘fresh’ tiddlywiki instance like the following:

title: $:/lithic/exporters/export-to-new-wiki
tags: $:/tags/Exporter
extension: .html
description: Export to Portable HTML
code-body: yes

\define saveTiddlerFilter()
[[$:/core]] [all[shadows+tiddlers]has[plugin-type]] [all[tiddlers]prefix[$:/]] -[prefix[$:/temp/]] -[prefix[$:/state/]] -[prefix[$:/status/]] -[prefix[$:/HistoryList]] -[[$:/StoryList]] -[[$:/boot/boot.css]] -[type[application/javascript]library[yes]] -[[$:/boot/boot.js]] -[[$:/boot/bootprefix.js]] -[has[plugin-type]field:platform[server]] [subfilter<exportFilter>] +[sort[title]]
\end

{{$:/core/templates/tiddlywiki5.html}}

This method works like I want, with the small complaint the file it creates is tiddlers.html, is there anyway I can (for this export option specifically) create a custom filename for the export? I’m not sure the best way to accomplish this, just let me know, thanks!
