How to set Total Runs limit type through command line?

Hi,
I want to run loadtest through command line. However, I only know -m can specify number of limit but I dont find a way to specify Total runs limit type which is right next to number of limit in the GUI. Can anybody tell me how to do it in soapUI 4.0.1?

C:\Program Files\SmartBear\soapUI-4.0.1\bin>loadtestrunner.bat
soapUI 4.0.1 LoadTest Runner
usage: loadtestrunner [options] <soapui-project-file>
-v Sets password for soapui-settings.xml file
-t Sets the soapui-settings.xml file to use
-D Sets system property with name=value
-G Sets global property with name=value
-P Sets or overrides project property with name=value
-S Saves the project after running the tests
-c Sets the testcase
-d Sets the domain
-e Sets the endpoint
-f Sets the output folder to export to
-h Sets the host
-l Sets the loadtest
-m Overrides the LoadTest Limit
-n Overrides the LoadTest ThreadCount
-p Sets the password
-r Exports statistics and testlogs for each LoadTest run
-s Sets the testsuite
-u Sets the username
-w Sets the WSS password type, either 'Text' or 'Digest'
-x Sets project password for decryption if project is encrypted


thanks
