Make custom Shift Grid

Hello,

I ´ve got one question.

I would like to make my own shift grid for national conversion between new an old datum (and reverse). I ´ve got an xls file with X, Y coordinates and their dX and dY. Is there any chance to make own shift grid in Bentley map or I will need other software.

I have read something about GSB files in GeoCoordinateData (http://communities.bentley.com/products/geospatial/desktop/f/5924/p/53164/123488#123488) but I don't  know if those files uses same values (X,Y,dX,dY) or they are completely different.
