This has nothing to do with the ELOG package, but only with your local configuration of that specific logbook.
You should contact your local ELOG administrator.
Or you might want to rephrase you question: do you want to have this text added in the text field when selecting the field specifier?
How that can be done depends on your specific configuration. Since you are apparently already using a form in the text field, it might be tricky.
I would like to have "Permis de verouillage et d'étiquetage 016685-68AF-0031" when I select it.
I don't found where can I make this change
