PivotTable Help - Multiple columns with same title

Hello,

I need help with PivotTable please. I have a sheet that has multiple columns with same names. i.e.:
Usages - Month 1 - Invoice - Month 1 - Discounts - Month 1

When I run the Pivot Table Report, under "Choose Fields to Add to the Report' it combines the columns with the headings 'Month 1'; is there any way to show me these fields as it appears on the data sheet and in the same sequence?

I would not be able to change the headings coz' sometimes I get over 50 sheets at a time.

All the help will be greatly appreciated.

Regards!
