Incremental mode

I'm working with a new plasma project  and the post procesor output the G code in incremental mode, wich have some adventages for the actual user, however when the file is loaded in QTplasmaC it is displayed properly, but when you move the torch to a diferent position (not the home) 
you can start the cutting process whic is ok, but the torch is not following the original drawing, is any way to make the drawing move to the begin point when in incrementalmode?  

I was thinking in any automatic way to set the origin to the current point if incremental mode is set in the pre-amble so the drawing is maybe reloaded to the new x0y0 position.

If it does not have to be 'G91' then you could easily create a custom Mcode with this in it:

This will set the current axis positions to zero (not sure if you need to zero the Z axis on a plasma).
