Dates on Potentials list

Hi,

When looking at my Potentials report, I'd like to see:

1. When any aspect of a contact's record was last modified. It appears that modifying the event due date does not trigger the Last Modified field.
2. Current event due date. I use this to organize my follow-up, and would like to see for each contact on the Potentials list when my next follow-up is scheduled.

Thanks for your guidance.
