PBR for locally generated traffic

Hello. I've need to dirrect traffic generated in fortigate (i.e. local traffic) to certain next-hop. On current i have 0.0.0.0/0 via tun0 for users, and i want dirrect locally generated traffic from fortigfate to nex hop tun2 for example.  I try following policy action: 

set input-device wan1

set dst 0.0.0.0/0

 set gateway 1.1.1.1 (example)

set outgoing-interface tun2

set status enable

But this action has affect for users behind fortigate. I wondered, why this acction has affect for transit traffic for fortigate, but not affect for local traffic for fortigate?  How i cat dirrect  local generated traffic to a certain interface? Thanks.
