To be honest I don't understand much from your text.
The suffix/prefix option is exactly what it looks like. It adds any text before or after the urls in the m3u.
What you put there is your cup of tea.
If you want to put there "STRING-1" then so be it.
We are not a tv-headend site.
You should declare your variables and ignore conditions on your tv-headend server.
I am sure, if there is a functionality and need for that in tv-headend, then it is or can be implemented there.
Ask their developers.
And sorry, but we won't create processor intensive features for things, only a few people would use.
