Changing Individual Header Label

Hi Steven.
Great plugin. I’m using it a lot.

Now I need to change the Header Label name for a page that has different content. Say the global is “Table of Content” and one page should have the header label “DAYS”

I was hoping to change it via the shortcode with attributes like [es-toc header_label=”DAYS”] but had no success. I did also check the Table of Content metabox place inside the page down below for individual settings.

My question is, how can i change the header label name on individual page or posts.

Thanks
Best regards
