SAPGui 7.20 and SapLogon.ini Question

We configure our install of SAPGui 7.20 to place a configured SAPLOGON.ini in C:\windows (WinXP).

Upon first use that file is then copied (as 7.20 is designed to do) to C:\Documents and Settings\<username>\Application Data\SAP\Common for the individual user.

So how do I go about resetting the "1st use" flag so that if I have updates to SAPLOGON.ini ... I can put the updated file in C:\windows .... and when the user starts SAPLogon the updated file will overwrite the one in their '\sap\common\ location"?
