Hi there 
You can have a look at File > Export... where you have a export configuration txt_taglist. It's probably the most basic one, which you can simply duplicate to have a working copy for your own needs.
Based on your example from above, I suggest using something like
$filename(txt,utf-8)$loop(%_path%)%_filename_ext%; %track%; %title%; %_length%
$loopend()
You can then create a new action group and add a new Export action to this group, selecting your export configuration as the export to be executed.
After that, you can perform this action again and again and again
