Creating Triggers Using Photoshop Layer Names in Character Animator

Hi community!

I noticed the Wilk.psd file Dave Werner created has layer names that include text like (n!) and (3!) that automatically create keyboard triggers when importing the PSD file into Character Animator.

However, these triggers are all unlatched.

Is there a way to create automatic latched triggers using similar layer name text directly in Photoshop? 

Thanks!
