This looks pretty good. But I have a question. Why add this feature? How does the replication step work? Will it lead to duplicate data? Looking forward to your reply

From the experience after actual use, several pages of /config/pluginhandle、/config/metadata、/config/dict have similar troubles.
Such as page /config/pluginhandle, a plug may need to add multiple fields, only the field names and descriptions are different.
In practice, I Every time add, need to select the PluginName, select the DataType, and select the FieldType to which the field belongs;
And add by copying, I only need to modify the name and description; Eliminates a lot of selection operations (selection is a costly operation and time consuming);

Realizing logic and editing is a logic; first query the details of the selected record, and then delete the ID; call the add-api when saving; there will be no duplicate data, if there is such a situation, it is also The backend API needs to be prevented;

If you agree and merge this PR, then I will add this feature to the /config/metadata and /config/dict pages.
