Single Transfer Order for Multiple Handling Units

I have been researchig the ability to create a single transfer order for multiple handling units. My assumptions are if it can be done that:

1) A transfer order can have a single source, so if the source document for the handling unit (delivery) is different, that means different transfer order

2) A TO can have multiple materials (line items) with different destination bins and quantities per bin

I looked at the configuration for TO Split, but it's not clear that this will handle my requirement.

I also saw this http://aq33.com/material-management/Articles-005798.html and it also says that my requirement can't be meant. I'm just checking before I tell my customer this cannot be done.
