How to make an entry under the header or callout using "Advanced URI" plugin?

I add an entry to the end of a note using this link
'obsidian://advanced-uri?filepath='+filepath+'&data='+new_data+'&mode=append&openmode=silent'

Is it possible to add the record not at the end of the document, but under some specific header or callout ?

So I wanted to refer you that plugins issues page on github, but it seems you’ve already posted there as well:

Yeah that’s me, but thanks)
