How do you sort each collection in a set of collections that is returned by a report?

I am using the reporting plugin to return all of the pages within a space that have a particular label. I am using the space-reporter to return the labels, and then filtering on the label that I want to give a collection of content, and then displaying the results.
I want to sort the returned content by modification date using the date-sort macro, but I cannot work out how to do this inside the report structure.
Here is my code as it stands:

{report-block}
{space-reporter:space=myspace}
{text-sort:space:name}
{space-reporter}

{report-body}

{report-table}

{local-reporter:space:labels in content}
{text-filter:label:title|include=mylabel}
{local-reporter}

{report-column:title=label = mylabel}

{report-on:label:content|separator=newline}{report-info:content:title|link=true}
* Created by {report-info:content:creator} on {report-info:content:creation date|format = dd MMM yyyy}
* Last Modified by {report-info:content:modifier}{report-info:content:modification date|format = dd MMM yyyy}
* Excerpt: {report-info:content:excerpt}

{report-on}

{report-column}

{report-table}
{report-body}
{report-block}

I would greatly appreciate any help with this.

Thank you.
