S pen handwriting transfer function with SwiftKey

Hi,
I'm a big fan of SwiftKey keyboard. Recently, I got the Galaxy Note 10, there is a feature in the Samsung keyboard with using the S pen, it can convert hand writing to letters. It is a cool feature, and for that I almost gave up SwiftKey.
I'd there any way I can use that feature with SwiftKey keyboard? Is there a specific app for that?
Thank you.
