Preview overridden and ovverriding animation at once

Hi, the issue I'm having is related to animation playback.

Basically, I have some movement animations for my player character. For each weapon, I made a separate animator layer, set to override. I'm currently working on overriding animations for the weapons (e.g.: the run animation for when a bow is equipped).

The issue I'm having is that I have to copy the legs' animation from the original animations (even though I don't change them), since there is no way to preview the weapon run animation overriding the original run animation.

This is an issue since changes in the legs animation don't "apply" to overriding animations (since they are actually overriding the legs animation with a copy of the basic animation).

I was wondering if I could preview the original run animation with the weapon overriding animation at once, so to remove the legs bit in the overriding animation while being able to view the full animation.

The only (not great) solution I have, is to enter play mode every time I want to test an overriding animation, but this is a very slow process when I have to adjust small movements.
