Is this possible? I currently append the following script to the end of the exported bookmark html file, but this should be a feature...

<h1>Sorted</h1>
<div class="right3"></div>
<p>
<script>
    let addDate = document.querySelectorAll('[ADD_DATE]')
    Array.from(addDate).sort((a,b)=>{       
        a = new Date(parseInt(a.attributes.add_date.nodeValue)).valueOf()
        b = new Date(parseInt(b.attributes.add_date.nodeValue)).valueOf()
        return a-b;
    }).forEach(el => {
        document.querySelector('.right3').appendChild(el)
    })
</script>
<style>
    a{
      	display: block;
        margin-top: 1em;
        margin-bottom: 1em;
        margin-left: 0;
        margin-right: 0;
    }
</style>
