After giving this suggestion some additional thought:

I think I will introduce two additional parameters for stemwall foundations which will make them more applicable for use as retaining walls in foundation design.
The two parameters will be:
Ftg. Bar Development: None, Hook, Full Ext., Full Int.
Ftg. Offset: 0.0 in (default)
Currently footings are drawn symmetrically with respect to the foundation wall, this will enable the user to offset the footing in or out (+/-).
