In a nutshell, here's what I did:
1) I made a new parameter called Occ_Load_Fixed. I know... we don't want a separate parameter, but bear with me.
2) In the Occupancy Key Schedule, I noticed that Assembly with Fixed Seating is the only use group where the Load Factor equals Zero.
3) In the Room schedule, I updated the calculated value.
The forumla used to be.... Area / SF_per_person / 1' ^ 2,
Now, the formula is.... IF (SF_per_person>0, (Area / SF_per_person) / 1' ^ 2, Occ_Load_Fixed)
Which in effect says: "If the use group is not Assembly Fixed Seating, then divide Area by Load Factor. Otherwise, use the fixed load parameter."
4) In the room schedule, I hid the Occ_Load_Fixed column.

Potential pittfalls? If someone creates another key value equaled to zero, then we may have unintended consequences.
Let me know if this works for you.
