I would like to propose a new column type: CFL
If we could put different CFL in each row, we could use Coda in a complete different way. There are situations where you want different formulas in each row, one example that comes to mind is my mailing list. For one mailing I would like to tab my client base, for another mailing I would like to tab my supplier base. There are work arounds, but they are mess: it would be a lot easier to put different formulas for retrieving the email addresses in each separate row.
I have run into similar situations previously, so it is not just this simple mailing example that would benefit from this suggestion.
