Make hole in a Genpri

How to create negative or hole in GENPRI?
I can modify input file in 3ds Max but can it be done in E3D?

GENPRI Elements cannot be modified, no options in E3D.

It should be modified at origin before importing into E3D

I thought we could create negative at EQUI>TMPL level or somewhere to affect GENPRI but no :(

Maybe there is some workaround besides modifying origin file:jaded:
