candle change orientation of board with gcode for 90 degrees

[oroborob]

Hi everybody, is it possible to rotate the board(boarders) incl. gcode in/with candle?
For 90°.
If I have a pcb 100x160mm for example.
I placed the pcb x=160mm length and y=100mm.
But candle always starts milling y=160mm and x=100mm.
After I change x with y in g-code file, the boarderlines are rotated 90°.
But g-code stays x160mm and y=100mm.
Only the boarderlines rotate.
Is it possible to rotate cpl. board, means borderlines & g-code for 90°, if yes how?
Hope I set the issue to be understandable.
Appreciate your help, resp. solution.

Thank you very much.
