The location of saplogon.ini file

Dear colleagues,

I would like to add temporarily a new SAP system to my SAP logon pad.

The problem is that current saplogon.ini file is managed centrally from a directory where users have no change access.

I need to find out how to point for another saplogon.ini file from my Desktop for example to be able to add a new SAP system.

I remember there is another SAP file that determined the place from where the .ini file is read.

Thank you!
