Allow multiple comparisons on one display

On BatchView we could place multiple comparisons on one display and have the current or running batch highlighted. This was great for a process with multiple batches running at different distinct phases on multiple units.

A simple example would if a batch that consisted of a fill phase, a cooking phase, and a emptying phase with different wait conditions between each phase.

If that simple recipe is running on 5 different units and each unit is at a different phase

The parameters or variable for a fill phase would be different then those for ether of the other 2 phases,  and so it would be nice to be able to have 3 comparisons on 1 display for the operators.

Perhaps add an event comparison object that would allow them to be dropped on another display.
