Autodesk sketchbook, how to add Blur Smear and sharpen brush on the IPad version

It's ridiculous that there's no smear, blur, or sharpen brush in the Autodesk iPad sketchbook's version. 

In order to resolve this problem, I first exported all three brushes from the free Desktop version. 

I transferred the files to my iPad using Airdrop and then imported all three brushes into Autodesk Sketchbook Brush Settings. 

They perform flawlessly, even when editing brushes, as if they were on the desktop version.

The smear, sharpen, and blur sets can be downloaded on this link.
