Delete/purge excluded IPs from previous dates

Is it possible to delete or purge excluded IPs from previous dates in which they were not excluded?

Anyone?

Yes. Possible.

Could you show me how? Is it as simple as running a MySQL query?

Bump

I tried looking at the database schema to run my own MySQL queries but was overwhelmed. Does anyone know where the I.P.'s are stored and the associated tables/rows?
