I have an Advanced PDF pick ticket that I would like to adjust the sorting on. We have a custom field on our bins for pick sequence (numeric field) and I'd like to sort the pick ticket items based on that. I've tried the following but it doesn't seem to be working.

<#list record.item?sort_by(["inventorydetail", "custrecord_bin_pick_sequence"]) as item>

Any idea if this is possible?
