@Paolo Di Trapani, Thank you for reaching out to us.
If you’d like your vendors to upload a different document for ID verification, you can simply rename one of the existing options using the Loco Translate plugin. This will allow you to customize the label as needed.
For guidance on using Loco Translate, feel free to refer to our documentation here: https://multivendorx.com/docs/knowledgebase/multivendorx-translation-guide/.
If you need any further assistance, we’re always here to help!
