Unique equipped weapon swap macro help

I have in my possession both blood moon daggers (Bloodharvest blade, one-handed)(Blood Spattered Stiletto, off-hand only) you can only equip one of these at a time. I have a third dagger Black Menace (one-handed). I would like to build a macro to swap between bloodharvest mainhand, black menace offhand. And swap between Black menace main hand, blood spattered stiletto off-hand while in combat. Unfortunately because of the unique equipped stat on the blood moon daggers I cannot seem make equipslot macros work. My intuition leads me to believe I’d have to place the daggers in backpack first before being able to move them around.

These are the macros in question I attempted to use but was met with multiple error messages “That item doesn’t go in that slot.” “You can only equip 1 item in the blood moon category.”

/equipslot 16 black menace
/equipslot 17 Blood Spattered Stiletto

/equipslot 16 Bloodharvest Blade
/equipslot 17 Black Menace

Does SoD have the equipment manager?

no can’t seem to find it.

Could try https://www.curseforge.com/wow/addons/gearquipper
it supports macros https://legacy.curseforge.com/wow/addons/gearquipper/pages/index/english/manual/macro-examples

Or apparently you can enable the built-in equipment manager in your settings? [according to Reddit]
