Dynamic tm1p.ini and homepages in Excel

Pointing all your users to a single TM1 Admin host is convenient but not flexible if you manage several TM1 services.
Each TM1 service might need different settings and you do not necessarily want users to be able to see the development or test services for example.

mytm1.xla is an Excel addin that logs the users on a predefined server and settings as shown on that graph:

With such a setup, you can switch your users from one server to the other without having to tinker the tm1p.ini files on every single desktop.
This solution probably offers the most flexibility and maintainability as you could add conditional statements to point different groups of users to different servers/settings and even manage and retrieve these settings from a cube through the API.

This addin also includes:
- previous code like the "TM1 freeze" button
- it loads automatically an excel spreadsheet named after the user so each user can customise it with their reports/links for a faster access to their data.

The TM1 macro OPTSET, used in the .xla below, can preconfigure the tm1p.ini with a lot more values.

The official TM1 Help does not reference all the available values though.
Here is a more complete list, you can actually change all the parameters displayed in the Server Explorer File->Options with OPTSET:
AdminHost
DataBaseDirectory
IntegratedLogin
ConnectLocalAtStartup
InProcessLocalServer
TM1PostScriptPrinter
HttpProxyServerHost
HttpProxyServerPort
UseHttpProxyServer
HttpConnectorUrl
UseHttpConnector

and more:

AnsiFiles
GenDBRW
NoChangeMessage
DimensionDownloadMaxSize

this also applies to OPTGET

WARNING:
Make sure that all hosts in the AdminHost line are up and working otherwise Architect/Perspectives will hang for a couple of seconds while trying to connect to these hosts.
