Feature to better utilise forms repeating section

Repeating sections are great but only in limited conditions. I would like to see them become more useful in workflows. I would like the repeating sections to be available as a form variable collection so you can add it to later task forms. We are currently handling this with loop by n operations. Parsing the data out into individual named variables and then using form visibility rules to add them to the task. We should be able to drop a repeating section start variable onto a task which generates dynamically based on the start form. either that or allow the repeating section data to be read back from SharePoint from xml. I can create an xml entry in SharePoint form the form but i cannot read it back into another form to be viewed/updated later.
