For a quick glance here is a video - Clubbing for Regional Funding Sources
This is feature of clubbing into billing based on different criteria. Earlier this was only enabled for insurance funding sources, now the clubbing is available for "Regional funding sources" as well.
If you now view any funding source of "Regional Funding Source" as the Funding Source Type, you can view the clubbing options as shown below.
Clubbing under Regional Funding Source works the same as way it works for the other funding source types.
