Design Studio - Localize Dialog Buttons

SAP Design Studio has a nice feature to define buttons inside of the footer of a 'Dialog' component:

The 'Dialog' component is one of the standard 'Container Components'.

My question is if there is a way to localize the text of these buttons, i.e. apply strings defined inside of a TEXT_POOL to these buttons? I see we can define the button text in the 'Add/Edit Dialog Footer Buttons' popup (see the screenshot), but I do not see a way to reference these buttons and to set their text in a script.

I would think that the 'Button Key' value would allow me to reference the button inside of a script function, but the editor does not recognize a component whose name is the button-key.

I am using SAP Design Studio 1.6 SP02 Patch 2.

Any insight or assistance would be greatly appreciated.
