Hidden tags, fields and title

[Mohammad]

Based on Tiddlywiki documentation (https://tiddlywiki.com/prerelease/#SystemTiddlers) system Tiddlers have $:/ prefix and are hidden from search and many lists!

The question is: Can it be customized to add more prefixes? 

For example I use some names and I want to keep them hidden e.g names starts with dot (.)

like 

tag: .mytag

field: .myfield

title: .mytitle

I know there is way to hide fields and or it may said used $:/ but I am looking for a configuration to let me simply add custom prefix!
