NGX flaps offset

Hello,I know the FSUIPC doesn't fully support NGX and this is not recommended using FSUIPC to set keys for the NGX but still..In the PMDG NG and the default 737 i can use the offset "x0BDC" but this offset doesn't work with NGX. could i use any other offset to set key for different flaps positions?thanks a lot for helping,
