Are there any DFF against Salesperson set-up tasks? (Manage Salesperson Account References...)

Summary:

Are there any DFF against Salesperson set-up tasks? (Manage Salesperson Account References, Manage Resources...)

Content (required):

I'd like to store alternate detail against salespersons (used to display detail depending on salesperson on the AR invoice). I highligthed flexfields into Fusion and look at "Manage Salesperson Account References" and "Manage Resources". I wasn't able to identify any DFF this way (even searching into the set-up tasks).
