Default [Q] Text recognition and entry problems with S Pen

Hi all, new here, so thanks in advance for the help!

I am trying to use my note 3 to write my data with and have it change it to a typed document. Right now I am using a pen and paper and it is slowing down progress. So to the Note we go. However, I am having 2 issues and need help.

1- Much of what I write is part numbers that are comprised of letters and numbers, for example IBM 82G1154. Despite my best handwriting anytime I write a mix of numbers and letters the typed conversion is always only numbers. So the above will get entered as 8261154. Is there anyway to get this correctly?

2- I find that I can write faster than it can translate and I often need to stop to let it catch up. I went and looked at a note 10 just to see if bigger was better and really was just the same. Is there a way to speed that up?

Thanks again in advance for any help.
