sudoedit restrict allowed file changes

Hello,

I am using sudoedit to allow a specific user to edit the configuration of rsyslog.
However, I am worried that some of the configuration parameters of rsyslog allows them to gain privileges on the system.

Is there a way one can restrict the changes that are allowed in the configuration file?

For example, changes could be passed through a regex, or an arbitrary validation script, before replace.

Also maybe giving up on sudoedit and creating a shell script that performs the required changes and allowing access through sudo is the solution here?
Though I'm also worried about the security of shell scripts themselves.

Please advice,

Thanks
