using custom field in reports

using custom field in reports

Hi,
We plan to use zoho books for our business (Dental Clinics) we start trail and we find it greater tools

We have one issue if you try to fixed it will be very helpful
Because we have deferent branch's we add custom field for sales invoices ,Expenses and other modules to segregate each branch but in reports we can't use the custom field to report and monitor each branch separated

Can you add this feature please? OR Can we have custom function when the custom field change automatically change the reporting tags
