Translate artwork with isometric grid change

[gabriel_komorov]

I've jus got this insane idea - what if making changes to isometric grid would affect already created iso objects?

Want artwork to be at slighty different angle? Change iso grid properties, click "apply to all" or something and BAM - everything on isometric grid gets translated to reflect new projection.

From previous conversations with Ben, who developed the feature, I can say that it is not possible. 

Affinity is not a 3d program, and has no understanding of the objects created on the isometric grid. It merely applies the distortion when the fit to plane button is clicked, and assumes that the user knows what they are doing. 

I asked whether Affinity could record which plane shapes were on, so that changes could be made, but it was pointed out that a single shape may be drawn so that it lies on two or more planes. So what is recorded in those cases?
