exim configuration editor

I was trying to modify the virtual_address_pipe transport via WHM editor since I need to add an envelope_to_add directive there.

Unfortunately I can't modify this section, only add the transport again. This result in an error, exim is complaining about 2 transports with the same name.

Now I can edit the exim.conf manually. But then I run into problems if CPanel updates exim.conf and overwrites my manual mod.

Is there any way to make the modification via configuration editor so it does not get overwritten?

 

Thanks, both answers are helpful and I knew them already

I would like to go with the editor, unfortunately I don't see a way to implement the needed modification.

The manual way is a workaround only.
