TMS320F28375S 100 PIN PZP Package EPWM Synchronization issue

I am interested in using TMS320F28375S 100 Pin Controller in my project. I need 6 EPWM's in synchronization. But in 100 Pin package the available EPWM's are 2,3,6,7,8,9,10,11. EPWM,s 7,8,9,10,11 are can be synchronized easily as seen in figure(in PDF). But the problem is to synchronize 6 with 7, 8,9,10,11. I am using Digital Compare module for another purpose. So, I thought to use GPIO, the path is EXTSYNCOUT - GPIO - X Bar - EXTSYNCIN2 - EPWM 4 5 6. Here the problem is EPWM 4, 5 are not available in the selected package. As EPWM 4,5 are not available, I wanted to know about the routing, is it directly from EXTSYNCIN2 to EPWM6, or any other method is available to Sync EPWM 6 with EPWM 7,8,9,10,11.EPWM_Issue.pdf
