iPad Pro with Apple Pen and Google Docs

I love my 13" MBP Retina, which I need for Development, but I want to know if an iPad Pro 10.5" would work for me when I am working on designs and documentation. My very specific requirement is can I used the Apple Pen in Google Docs? I want to quickly and easily insert drawings, via the pen, directly into the Google Doc I am working on. I do not want to work on Google Docs, switch apps, draw the sketch of a design and then paste it into Google Docs.

If it does the above directly, I will buy one but no one in any store has yet to give me the answer.

Thanks,

Paul
