Should you not self report test score if you don't intend to send the official report

If a college will accept either the ACT or SAT and DS sent ACT scores directly to college, is it not correct then to self report the SAT score also on the common app? Meaning, I don’t want to pay to send the SAT scores bc they already the ACT, but at the same time the SAT score is respectable and would like to list it.
