Text-to-speech & punctuation

Hi,

When creating closed captions with the "Add Closed Captions" option of the text-to-speech feature, the punctuation is removed (all comas, full stops, question marks, etc.) are removed.

Is there a way to prevent that ?

It is very time consuming to manualy add them by editing the closed captions in the "Properties" tab.

Thank you for your help !
