When bundling items, it would be good if you could turn on that they are able to submit more than one of the same item in the bundled form.
For example, we have a Distribution List form. For Auditing, we have one Distribution List group per form that they can log access to so bundling it would mean to update one distribution list they would have to log it but then go out and log yet another.
If in the bundling you could say, I need 2 or more of these - they could update multiple DLs on the same bundle. Meaning they could say I want a bunch of people removed from this Distribution list but then added to all these ones instead. That way they are all linked in the bundling and processed under the same form but all going to the right place and all on separate forms for auditing.
