To Hit Bonus for Custom Actions

I wonder what it is that they decide is priority to fix?  It sure doesn't make any sense to me.

I'm having an issue where my polearm master has acquired a +2 spear (a Blood Spear, actually), and I wanted to give that spear its own Pole Strike custom-action, labelled as such to reduce confusion and overhead. Instead I have discovered that, while existing actions allow a custom to-hit bonus, custom actions do not, despite allowing a flat damage bonus (oddly labelled, but still) and so many other modifications ... just not that one, the part that's the attack roll, even on "weapon" custom actions where it's most important.

I've also discovered that people have been asking for this oversight to be remedied for at least seven eight years.

I'm not happy about it.
