Reimporting term should overwrite all categories and not create a duplicate term
When reimporting terms/translations/context with updates, if there is a change in context - POEditor will duplicate the term and create a fresh entry rather than overwriting all categories being imported. This make mass updating of context impossible.
Kindly note that the uniqueness of a term is given by the term-context pair: https://poeditor.com/kb/duplicate-terms
Therefore, if you import the same term with a different context via the UI, a new term will be created.
However, if you want to update the context of an existing term in your project, you can use the API with this method: https://poeditor.com/docs/api#terms_update
