Synchronize two FTMs

I'm trying to figure out how I can do a software synchronization of FTM0 and FTM1 timers.

 

It looks like I can write to FTMx_SYNC[SWSYNC] for each module and have them setup to reset the CNT value.  However, since that is two separate writes for FTM0 and FTM1 they likely wouldn't be exactly in sync.

 

It looks like I could probably use an external HW sync to drive both modules, but it would be easier if I could do it with a SW sync.
