Running multiple Soapui Projects from the command line

Hello,

I'm new to SoapUI and automation in general, so I apologize in advance for asking a question that appears to have already been asked.

I'm able to execute a single project using "testrunner.bat "c:\my projects\my-project.xml"" from the command line.  

I have about 10 soapui projects that I want to execute from the command line from 1 keystroke.
(doesn't matter the order they are executed in.)

I was thinking of creating some type of file and using a for loop to iterate through and at each step in the loop I could execute the testrunner.bat and just point it to a different project.  

I'm just not sure what type of file to create and how to execute it.  Any information would be greatly apprecaited.  I found alot of similar questions online, so feel free to link to those.  I'm currently running Windows 7.

for(int i = 0;i<=10;i++)
{
     if (int i = 0)

     {
      testrunner.bat "c:\my projects\project1.xml"
     }

     if (int i = 1)

     {
      testrunner.bat "c:\my projects\project2.xml"
     }

     if (int i = 2)

     {
      testrunner.bat "c:\my projects\project3.xml"
     }

     if (int i = 3)

     {
      testrunner.bat "c:\my projects\project4.xml"
     }

     if (int i =4)

     {
      testrunner.bat "c:\my projects\project5.xml"
     }

     if (int i = 5)

     {
      testrunner.bat "c:\my projects\project6.xml"
     }

     if (int i = 6)

     {
      testrunner.bat "c:\my projects\project7.xml"
     }

     if (int i = 7)

     {
      testrunner.bat "c:\my projects\project8.xml"
     }

     if (int i = 8)

     {
      testrunner.bat "c:\my projects\project9.xml"
     }

     if (int i = 9)

     {
      testrunner.bat "c:\my projects\project10.xml"
     }

}
