Help with Highly Customized Gunslinger

[Doonamis]

Hey, I need some help figuring out if there's any way to make the following work. I do have this character, and it would be helpful to figure out how to properly model him in my Herolab on iPad if possible.

Gunslinger 5 (Musket Master), Alchemist 2 (Trap Breaker), Fighter 7 (Weapon Master)

My gunslinger took two levels of Alchemist for the discovery to gain a third arm. He now two weapon fights with Muskets. One is sovereign glued to the hand of his "firearm".

I can't figure out how to TWF with two handed weapons since I have the extra arm. I'm guessing that Herolab never intended for this, which is fine, but I'm just curious if there's anything I can do to make this work in Herolab.

Thanks

There is a weapon ease of use adjustment you might look into

Im not familiar with firearms, but you need two arms per weapon. IE 4 to dual wield dual 2h weapons
