So this is an HSQC and a 3D Noesy or something? If you want to keep the 2D fixed and re-reference the 3D to that and (say) there is a repeated 1H dimension in the 3D then when you first open up that dialog it will map the 2D 1H to the first 3D 1H but if you double click in the "Reference by Peak" dialog on the second 1H row in the "Fixed Dim" cell it should pop up an option to make that the dimension that the 2D 1H gets mapped to. At least that seems to work for me.
Doing many spectra in one go is a trickier issue because it would need an upgraded dialog, I will look into that.
I guess you noticed that it is the last peak selected that is fixed and the other peak that is re-referenced.

If you chose to reference a 3D to a 2D spectrum it gives you the option to choose which dimension to match to which, however if you want to reference a 2D to a 3D it automatically assumes that 2D.F1=3D.F1 and 2D.F2=3D.F2 (which in my case is not true). This happens even if the dimensions are not compatible - I lost my 2D HSQC as it tried to shift the carrier to match the CA region... This is a pain as I have referenced all my 3D's to each other and now I need to re-reference them all or do the 2D reference manually.
