[Macro Help Request] Macro for Improvised Weapon in 5e

I have a player that picked up Tavern Brawler feat specifically because her druid often throws or uses handy objects instead of carrying weapons. Whatever comes to hand. I wanted to make a quick macro for the player to pick "Attack or Throw" then "Damage Type" - so if they want to throw a mirror, it might do 1d4 slashing, ranged, versus striking with a nearby pig which would be 1d4 bludgeoning, melee. So it'll always roll 1d4 of a damage type, plus the relevant stat proficiency...  May not be able to macro it, I understand, and having a pro subscription I can write an API, but I'm not experienced enough to know if this is macro-possible or not. Edit: This brings up a question of if the feat is usable while wildshaped and I'm not sure it's ever come up before... 

Assuming the Roll20 official D&D 5e sheet, you should be able to adapt/tweak this Generic Attack  and Damage (Seperately prompts you for the attack modifier, the damage dice(without the mod)  and the damage modifier, so it handles crits correctly) &{template:atkdmg} {{mod=Generic Attack}}  {{r1=[[ 1d20+?{Attack Mod|0} ]]}} {{always=1}} {{r2=[[1d20 +?{Attack Mod|0}]]}} {{attack=1}} {{damage=1}} {{dmg1flag=1}} {{dmg1=[[?{Damage Dice} + ?{Damage Mod} ]] }} {{dmg1type=dmg1type}} {{crit1=[[?{Damage Dice}]]}}

Giant Octopus springs to mind, but if your player is choosing to do 1d4 damage with their entire turn, instead of using an auto-restrain, 15ft attack, you probably need to increase the encounter difficulty :) But yeah, throwing a ?{Damage type|Bludgeoning|Piercing|Slashing} into the {{dmg1type}} field should do the trick. Probably worth mentioning that, homebrew aside, there are very few situations where this matters beyond narrative. Skeletons, some types of oozes... I can't think of much else. Blanket BPS resistance/immunity is common, but differentiating between them is rare.
