Hi Kim,
It sounds like you may have tried these already but there are several group data tags that will pull in this information for all group members within one email:
{[C-GROUP ORDER DETAILS]} creates a table that displays a list of each group member's order, including the date ordered, type of order, item, type of item, amount ordered, amount paid, and balance due.
{[C-GROUP ORDER SUMMARY]} creates a table that displays a list of each group member's order, including the item, price, quantity, and amount due.
I prefer the look and feel of the {[C-GROUP ORDER SUMMARY]} data tag as it creates a more modern looking table and shows all group members as well as the group total.
