How can i pass the name of a project to a different project as a variable using project templates

Hi,

I have a template where i have two projects 

Lets say Project1 , Project 2

I am using customparameters.

Attached is the .vstemplate I am using

<VSTemplateVersion="2.0.0"Type="ProjectGroup"xmlns="http://schemas.microsoft.com/developer/vstemplate/2005"><TemplateData><Name>TestFormat</Name><Description>An example of a multi-project template</Description><ProjectType>CSharp</ProjectType></TemplateData><TemplateContent><ProjectCollection><ProjectTemplateLinkProjectName="$safeprojectname$">
				TestFormat\MyTemplate.vstemplate</ProjectTemplateLink><ProjectTemplateLinkProjectName="$safeprojectname$Application"  variable=$Myvaraible$>
				TestFormatApplication\MyTemplate.vstemplate</ProjectTemplateLink></ProjectCollection>

<CustomParameters><CustomParameter Name="$FormatCode$" Value="$safeprojectname$"/>    </CustomParameters><ProjectItem ReplaceParameters="true">
        default.cs</ProjectItem>

</TemplateContent></VSTemplate>


The issue I have is that I would like to set a varaible(variable=$Myvaraible$)

maybe in the second project that is the name of the first project. So that when i create the template and the second project is initialised , I can set that variable in a code behind file.

Is there such a thing as global variable I can set and read ?

So if the code behind had something like 

$Myvariable$.GetItemList();
it would put the name of the required project name.


Thanks
