Change Text of the Buttons in UMB_PRES in SEM-CPM-BSC

Hello,

I want toi know if there is easy way to change the text of the button in the TCode UMB_PRES.

I want to chage the text that says "Drilldown" to an spanish text. And where it says "Score" & "Status" in the graphics part of the Analysis of the measure.

Or do I have to touch code to do that??? Is it in a table????

Thank you very much & Best regards...

Pablo Mortera.
