I discovered another way and hope, my English is good enough to explain it.

You download a Photoshop-Brush and safe it as an .ufo.
You safe it in the "stamps" file of your PI. Then you open a
new sheet and go to your stamps - the second line says "add stamps" or something similar.
Choose your new stamp and stamp it.
Then you have the brush on your sheet.

If you have problems understanding it due to my horrible English and are still interessted
in the method, please contact me, I'll explain it with screenshots.

Have a great sunday
