Dear,
In our setting, we provide many available items to user.
However, we do not intend to provide select many items.
Since we don't have any choices, we make it failed in "Step" when too many items selected.
Is there any way to limit the number of selected items in multi-selection box?
If it supports in "Specify Build Option" page, we could block abnormal build without triggering the build.
We hope it will be implemented in next QB major version, if current QB is not supported.

Thanks.
