Captions improvements for faster editing - Premiere Pro

Hi! 

I use captions alot when editing in Premiere Pro. And would like to see a smal but efficent improvement on the UI of it. When editing each text box there would be much faster to have a few different buttons for fast edits. Like uppercase letters in the begining and period or commas in the end of each sentence. Just these three buttons would make the workflow a bit faster. 

Thanks!
