Process Explorer: Toggle to visualize full process, don't aggregate steps

Currently steps are visually aggregated within the process explorer app even if they occur more then once within a variant.

If this occurs you will see loops/connections going back into the same step which as a result makes it very difficult/impossible to interpret the actual sequence of steps for said variant.

A possible solution to this issue is to introduce a "toggle" which cancels the step aggregation and shows the full process meaning that if a step is repeated it will occur more then once in the visualization.

Alternatively some sort of animation showing the actual sequence of the process execution might also help
