Designing a Scenario for multiple user injection rate

Hi Experts,

Please help me to design a loadrunner scenario for 6800 Vusers.  I want to inject first 5230 Vusers at 1 Vuser every 2 seconds and the remaining 1570 Vusers at 1 every 4 seconds

I have 13LG boxes with high end configuration. A maximum of 11 terminal sessions can be opened in each LG and max of 50 Vuser each terminal.

Thanks in advance
