[Dx4win] Label printing question

[Bill Barr, N4NX]

I Notice that a lot of QSL managers use DX4win to print labels for outgoing QSLs--I do for PJ6A.  Many of their labels are formatted as follows:

XV2A confirms QSO [s] with N4NX

I haven't seen or read how you modify the Call Sign top line to look like that.  Can anyone help?

Thanks
