Modify default probability percentage in an Opportunity

Modify default probability percentage in an Opportunity

Is it possible to override the default probability percentage at the Opportunity level in Zoho CRM?  I know you can change the default percentages globally, but if we have a Stage 5 deal that defaults to 80% and we learn that a new competitor has been brought in to the mix that has previous relationships, we would want to drop the probability percentage to 60% for that specific situation.  It would show we have more risk with the new competition.  Moving it back to Stage 4 would not make sense as we are firmly in negotiate stage.  Can this be done?  Thanks
