Workflow firing when record is Edited

Workflow firing when record is Edited

I've seen two different requirements posted on this forum regarding how many times a workflow should fire when a record is edited:

http://help.zoho.com/portal/en/community/topic/workflow-rules-not-triggering

My requirement is for the workflow to get triggered every time the record is edited after it has reached a certain state. This is so that an administrator can be alerted and change his/her actions accordingly based on different fields that could be modified.

Can Zoho make it an administrator-specified option as to whether the workflow is to fire everytime or only the first time a record is modified?

Thanks,
