FORMULA COLUMN EXECUTION

Question

Hi all!
I am using Report Builder 6i.
My report has several Groups (shown below)(that are user created, ie. not created due to the query).
Group_Organiser1
------Group_Organiser2
------------Group_Organiser3
-------------------Group_Organiser4
I have a Formula Column(FC) in Group_Organiser1. I want this FC to be executed only once, regardless of the number of rows included in/by the group. Hence, i want the FC to execute only when the value for Organiser1 changes (Eg. if there are 4 rows with Organiser1 = O1 and another 3 rows with Organiser1 = O2, I want the FC to execute only once when value changes from O1 to O2).
Currently the FC executes each time a row (that meets the grouping criteria, ie. 4 times for O1) is included in the group.
Hope this is enough information to solve this problem.
Eagerly waiting for any response...
Thank You.

Thanx Aguero for your reply but sorry to say it does not solve my problem.
I really need to control the number of times the FC executes because if it executes too early (or too often) it does not count all the people below Organiser1, hence i need it to execute just before the value for Organiser1 changes.
This is my 'program logic' for the FC:
-depending on who(hence designation) is retrieved below Organiser1, increment the User Parameters(UP) :AC, :DC, :MOMM etc (which indicate/represent the various designations).
-then when Organiser1 is about to change, using the non-zero UP return an output of the form "AC: 1, DC: 3, MOMM: 2"; and also reset the UPs to 0 (zero).
So, you can see that if the FC executes too early (or too often), the UPs are reset too early.
To give an analogy, my requirement (for the FC) is similar to 'Reset At' property of Summary Columns; my FC needs to Reset At/Execute only when Organiser1 changes.
(Another problem with what Aguero has suggested is that Organiser1 values are retrieved from the database so i have no way of knowing who is going to be retrieved.)
Thank You.
