Change server in backup job

In our enviroment we add a second IP to certain servers in a other VLAN Now the backup must run on that IP so the traffic will pass in a other VLAN.

We can't use the host-file for this change because there is running other software on this server, so we must change the server in the job without chaging the sellection. Mostly it's a complex selection, so it would be easy to change only the server where the job points to. Is this possible or must I recreate every backup job?

Tthx for helping.
