Draw Line / Draw Simple Material on Shipping

Hello
I want to do activity mentioned in topic. However on shipping configuration nothing that starts on prefix draw will show up. As I am able to do some optimization tricks in C++ that allows to render many thousands of these entities without losing too much performance I don’t want to lose this ability.
Is there a way to keep these draw calls on Shipping configuration ? If not: how it can be handled ( don’t tell me - use Widgets )
