OpenVPN Client Routing in External File

I have about 10 different VPN servers I connect to via the OpenVPN client.

I have a list of about 70-80 IP addresses that I want to not run through the VPN. I have set them up as route commands in each of the opvn configuration files.

This is quite a tedious solution as anytime I need to add or modify one of those IP addresses then I have to modify 10 different opvn files.

Is there a way to have a single external file which contains all my routing commands which I manage, and just have a single command in each of the opvn files that tell them where the routing commands are?

Thanks in advance!
