Help with settings directory in Converter <Text file - Tag>

How can I configure the function <Converter → Text file - Tag> so that, upon opening, it defaults to %_workingpath% (the "current working folder", fig.2) instead of the previous one (fig.3)?

I tried experimenting with the "Favorite directory" (fig.1) using different placeholders (default was blank):

%_directory%	
%_path%
%_parent_directory%
%_workingdir%
%_workingpath%

But whenever I open the dialog with Alt+4, it always defaults to the previous folder.

Any suggestions? Thanks!

I think that the detected behaviour is currently the only way to do it.
Right now there is no way to modify it.

Here is my workaround.

After creating and saving the source text file, I copy it to a designated folder whose path (and file name) never changes. When pasting, I allow the previous text file in that folder to be overwritten. This way the same source folder and my "standard" text file name always appear on opening the Convert Text to Tag dialog.

Before converting, you can use the Preview button to verify that the source data is as you expect.

I had imagined a simpler solution, but your approach might end up making things more complicated for the user. I'm about to finish an additional Python tool, and at this point I’ll have to integrate direct file writing with a dedicated dialog window in %_workingpath%.
Thanks a lot to both of you for your replies.

Best regards
