When installing an additional instance of Essentials, prompt for the creation of an additional Application Pool

When installing an instance of Geocortex Essentials and going through the Post-Installer the default Application Pool "EssentialsAppPool4" is selected.   This means that in the case that you are installing an additional instance of Essentials that same Application Pool is selected.  This can lead to several Essentials instances within the same App Pool.  This can be acceptable in some cases, however in high-load cases having multiple app pools seems ideal.  My idea would be to have the Post-Installer check if the default app pool has an existing application in it, and if so prompt to create a new app pool.
