converting from an 8 bit to a 10 bit color space

This is a two part question. I'm ultimately trying to find a workflow for converting 8bit to 10bit footage. So these questions are in that context, but if there are easier ways then I'm very open to suggestions.
First, I can manually change from 8 to 10 bits in After Effects CC. Simple menu adjustment in Project Settings and it's done. Is there an equivalent menu adjustment I can make in Premiere Pro CC to change the color space to 10bit? If so, will it behave like in AE where it will change the color space to 10 bit even if the imported file is in 8bit?

Second, I'm having trouble with my 8 to 10 bit workflow. I convert to 10bits in AE, export as Quicktime DNxHD making sure that "Trillions of Colors" is check marked, and open in Premiere. However, once I'm in Premiere, the file continues to be treated as 8bit. If I open the same converted file in AE I can change the color space to 10 bit in project settings and I immediately notice a difference for corrections and effects. But I can't figure out how to accomplish this same thing in Premiere. I've tried to research this extensively and just can't find an answer so I apologize if this has already been asked. Any and all help would be greatly appreciated.

Thank you!

If you want to put 8bit video into a 10bit container just save your footage as 10bit DPX files or Quicktime DNxHD 10bit 185 data rate. It is important to set the DNxHD codec settings to 10bits RGB Levels. If you are doing broadcast delivery, you should set the codec to Rec709 and check the output with a calibrated reference monitor.
Hope that helps.
