Hide "control_after_generate" for primitives?

[ThioJoe]

I have several primitives to control values like the number of steps, cfg value, batch size etc. And for all of them, the extra line for control_after_generate is totally unnecessary, and makes the boxes a lot larger than they should be, and doubles the amount of settings. It just clutters up the area that I have designated for setting the parameters. Is there a way to hide them?
