Using Global Damage Modifier on Token actions

So i'm trying to setup an elven accuracy token action for my hexblade, and I like to use a global damage modifier to add in hex damage. I have got a workable macro going but can't figure out how to make it roll the global damage mod. I have it using global atk mods just fine. Am I missing a step here or is it just not possible to make macros use global damage mods? I know I could just add hex as damage2, but I like having the ability to toggle it on and off. Macro below, thanks!:

@{Markus Shadowhawk|wtype}&{template:atkdmg} {{mod=+@{Markus Shadowhawk|spell_attack_bonus}}} {{rname=Eldritch Blast}} {{r1=[[3d20kh1cs>19 + @{Markus Shadowhawk|spell_attack_bonus}[SPELL]]]}} {{normal=1}} {{attack=1}} {{range=120 ft}} {{damage=1}} {{dmg1flag=1}} {{dmg1=[[1d10+@{Markus Shadowhawk|charisma_mod}[CHA]+@{Markus Shadowhawk|PB}[PROF]]]}} {{dmg1type=Force}} {{crit1=[[1d10]]}} {{charname=Markus Shadowhawk}}{{globalattack=@{Markus Shadowhawk|global_attack_mod}}}{{globaldamage=}}{{globaldamagetype=@{Markus Shadowhawk|global_damage_mod_type}}}

You don't have anything in the global damage field of the macro shown here: {{globaldamage=}} Put some dice in there and save the macro. It should do some damage.

Sorry wasn't clear enough. I know how to add the damage like that, but that sets it to always add the global damage mod which is not what I'm after. I was hoping for a way it would only add that when I have it toggled on the character sheet.
