Replacing Zombie Walk+Adding Sounds to Walk Based on Gender

Hi! This is a two part question. It's about SAC's Zombie Apocalypse mod here

In the earlier versions of the mod, the Zombie sims use a walkstyle with their arms stretching out which I vastly prefer but ofc the earlier versions of the mod are broken. It's still included in the current version's "Animation V1" package file but it's not linked to anything. Instead, they use a different walk (in "Animations 2.0" package file) which just makes them look drunk. The main Mod package file references the new one under a Locomotor Builder and Walkstyle but I can't seem to link the old walkstyle to it. Deleting the new one just makes the Zombie sims use the default Sim walk.

My second question is, is it possible to link custom sounds to an animation based on the Sims' gender? In the aforementioned mod, Zombie sims weirdly enough use cowplant sounds attached as Event within both the idle and walkstyle and it doesn't distinguish on gender. Is it possible to add custom sounds (specifically the Zombie groans from Sims 3) and add them to the animations but specify gender? So for example, only female Sims would use the female soundfiles.

Thank you!
