Is it possible to have redact function on iPad Pro with Apple Pencil

Hi there, I have been a DC pro user for someday. I am just wondered if there is any redact function on ipad version? It will be more convenient to use stylus to redact the pdf instead of using mouse. I tried the one on x86 surface pro 3 with stylus before the tablet died and it was great. Is there any way to apply this mighty function to any subscribers or paid users of DC pro?
