Subattacks that can ignore penalties only?

So I have a sniper type build in Savage Rifts.

He has Calculating and Marksman, plus trademark weapon. Modifying the attack rolls for trademark is easy.

And doing a sub attack for Marksman where it's just +1 is easy too. But how do I set it up sub-attacks for 'ignore penalties'?

I'm very new to FG, so I'm sure this has been answered, but I couldn't find it.

Thank you!

The problem here is that Calculating allows you to ignore up to 2 points of ANY kind of penalty.

If it was specific it is an easy thing to deal with because the ruleset code checks for anything that offsets a specific type of penalty rather than "all penalties".

So in this case (because of Calculating) you would have to manually apply the reduction based on what is going on with the shot.
