How can I set testsuite property in maven like we set project property in projectProperty tag?

Hi,

I want to set testsuite level property in maven

something like,

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>src.main.resources</groupId>
    <artifactId>soapui-maven2-plugin</artifactId>
    <packaging>jar</packaging>
    <version>1.0-SNAPSHOT</version>
    <name>Maven 2 soapUI Sample</name>
    <url>http://maven.apache.org</url>
    <pluginRepositories>
        <pluginRepository>
             <id>smartbear-sweden-plugin-repository</id>
        <url>http://www.soapui.org/repository/maven2/</url>
        </pluginRepository>
    </pluginRepositories>
    <build>
        <plugins>
            <plugin>
               <groupId>com.smartbear.soapui</groupId>
                <artifactId>soapui-maven-plugin</artifactId>
                <version>5.1.0</version>
                <configuration>
			<projectFile>Offline-soapui-project.xml</projectFile>
			<junitReport>true</junitReport>
			<outputFolder>${project.build.directory}/reports</outputFolder>
			<testSuite>SmokeTestSuite</testSuite>
			<testSuiteProperties>
			<testSuiteProperty>serviceEndpoint=${serviceEndpoint}</testSuiteProperty>
			</testSuiteProperties>
		</configuration>
                <executions>
                    <execution>
                        <phase>test</phase>
                        <goals>
                            <goal>test</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>   
        </plugins>
    </build>
</project>

so that when I run soapui project from command line and pass testsuite property value as

mvn - test -DserviceEndpoint=http://some_url

it should set testsuite property in the soapui project.

Any help would be greatly appreciated.

Thanks
