How to setup TestSuite Priority for a Project with multiple TestSuite

nmrao: Once I fully understand what the requirement is, I have a groovy script that should suffice with a few minor tweaks. 

Here is the script you would need:

Create another suite, add a test case, add a groovy script and use below script

import com.eviware.soapui.support.types.StringToObjectMap

//Modify below as needed
sequenceSuites = ['TestSuite1']
parallelSuites = ['TestSuite2', 'TestSuite3', 'TestSuite4', 'TestSuite5']

//DO NOT MODIFY BEYOND THIS POINT
def project = context.testCase.testSuite.project
def runSuite = { suiteName, async = true ->
	suite = project.testSuites[suiteName]
	suite.run([] as StringToObjectMap, async)
}
println '=====================Running Suite  Sequencially Start====================='
sequenceSuites.each{ runSuite(it, false) }
println '=====================Sequential Execution End==========================='
println '+++++++++++++++++++++Paralled Execution Start++++++++++++++++++++++++++++'
Thread.start{
	parallelSuites.each { runSuite(it) }
}*.join()
println '+++++++++++++++++++++Paralled Execution End++++++++++++++++++++++++++++'
println 'completed'
