Cross-reference a section using section ID

[kc-li]

Hi, I'm trying to write my thesis using the officedown, and am wondering if the funtion of cross-referencing section would support using a section id, as the bookdown package does.

For example, given the following section titles

# Introudction of the language
## Geography of the language
## History of the language

The current reference format is: cf \@ref(Introudction-of-the-language).

It would be nice to allow assigning section id, so that later on even if the section title changes, we won't need to go through the text to change each occurrence.

# Introudction of the language {#Intro}
## Geography of the language {#Geo}
## History of the language {#History}

The desired reference format is: cf \@ref(Intro) and \@ref(Geo)
