option to add category: "[[Matter-highlights]]" in metadata template

[iamrobmat]

So I wanted to add category: "[[Matter-highlights]]" in metadata template while syncing files and it does not work. I want to separate my notes from all the rest.

I tried two options:

1. added it at the end:
   category: "[[Matter-highlights]]"

2. added it at like other data:
   {% if category %}
   category: "[[Matter-highlights]]"
   {% endif %}
