Split Panel Function

When using MDF panels on certain projects, we can split the lengths or widths of panels.

For example: 

Panel required: 900 x 1220 but it will not fit, so a new panel is added to the cut list

I can split them since this is MDF into 2 pieces of 450x1220 during the input instead of creating multiple panels (manually calculated)

Panel names should be updated also to include the name-A, B, (1,2, I, II,  etc..

If the split is removed, the Panel sizes should also update as if it was entered, and the calculation should produce 1 full panel as normal input.

Hmmm, this sparks another idea for joining lumber boards into a large panel (such as table tops)!!
