Push routes dynamically for openVPN

I know that from server.conf I can do this:

push "route 192.168.20.0 255.255.255.0"

but, is there a way to push routes dynamically? I have an API call that returns all routes the vpn clients will need, so in case of some route change, the client will just restart the vpn connection and it will have the new routes. Is this possible? how? I want to manage this from the server side.
