How to Display Customer GSTIN in Sales/Item List Report?

Hi Team,

I'm using Aronium for billing in India and have added the customer GSTIN under the "Tax Number" field. While the GSTIN is shown in invoices, I need it to also appear in the Sales or Item List reports to track B2B sales for GST compliance.

Is there a way to include the customer GSTIN in these reports? If not, is it possible to customize the report to show this field?

Thanks in advance!
