CLI To Create Forced Subs SUP from Source SUP

[AYColumbia]

Please consider adding to the command line interface the ability to create a forced-only SUP from a source that has all subs with some flagged as forced, e.g.,
SubtitleEdit.exe /forcedonly /convert "full_eng.sup" "forced_eng.sup"

Thank you.

I'm closing this request as the feature already exists and you have to use the parameters correctly. I did NOT have the input params set up correctly in my OP. Thank you for this feature. :) Here's how to correctly specify so you can pull the forced subs into a separate SUP file.

SubtitleEdit.exe /convert "D:\Media\full_eng.sup" Blu-raysup /forcedonly

If you specify an output file name, make sure there's no space after the colon, i.e.,
SubtitleEdit.exe /convert "D:\Media\full_eng.sup" Blu-raysup /forcedonly /outputfilename:"D:\Media\forced_eng.sup"
