Power BI Display Column Name

Hi , 

I have a  request from the user where I need to display the name 'Payment Mode' on top of the different payment modes selected in the column section .

If you see the screenshot above, 'TransactionDate ' is selected in the Rows section, and the Payment Mode is selected in the column section as the user need to see the data in this format where CA,CH,IC are different payment modes.

But the user also want to see the name PaymentMode' on top of it so as to know these are different paymentmodes.

Is it possible to do that? Could help?
