Split Tunnel example question

[jriker1 1]

I am looking at the split tunneling example 

 

https://airvpn.org/topic/9549-traffic-splitting-guide-to-setting-up-vpn-only-for-torrenting-on-windows-thanks-to-nadre/

 

The last part where it creates the additional routes in the batch file.  Is it possible to use a -p for persistent if I don't want to create them each time or will openvpn override those settings each time it launches?

 

Thanks.
