So essentially what I did was click the attack button on my PCs character sheet, hit up, copy that, then add it to a macro so my players could attack without having to enter their character sheet.  My concern now is that I have to somehow add the benefits of Great Weapon Master to this. Some minor googling came up with simple macros that do this like /roll {1d12ro>2}  Meanwhile my macro looks like this: @{Darrack Stonechest|wtype}&{template:atk} {{mod=+8}} {{rname=[Greataxe +1](~-KhEZO4qCEFwn0VPgpjh|repeating_attack_-KhEdBFJdp3GieJykWun_attack_dmg)}} {{rnamec=[Greataxe +1](~-KhEZO4qCEFwn0VPgpjh|repeating_attack_-KhEdBFJdp3GieJykWun_attack_crit)}} {{r1=[[1d20@{Darrack Stonechest|halflingluck}cs>20 + 4[STR] + 1[MOD] + 3[PROF]]]}} @{Darrack Stonechest|rtype}@{Darrack Stonechest|halflingluck}cs>20 + 4[STR] + 1[MOD] + 3[PROF]]]}} {{range=5ft}} {{desc=}}  ammo= @{Darrack Stonechest|charname_output}  Great Weapon Fighting says: When you roll a 1 or 2 on a damage die for an attack you make with a 
melee weapon that you are wielding with two hands, you can reroll the 
die and must use the new roll. The weapon must have a two-handed or 
versatile property for you to gain this benefit.  So basically what I need is to somehow change my macro so that it if it gets a 1 or a 2 it will reroll ONCE and print a new total.  Any advice would be appreciated.
