Hi,

Currently if you want to present multiple layers on the same Workshop Gantt Chart, they need to have the same level of grouping. I have a use case where two of my layers share the same first level of grouping, but one layer then goes on to disaggregate by a second level of grouping while the other only has the initial level. You cannot do this currently and as such need to artificially group by some constant property to get the Gantt Chart to show. This requires the creation of unintuitive ontology objects and it would be ideal if the chart accepted layers with different levels of grouping natively.

It could look something like this:

Group 1 \< space\> | ======== == Layer 1 (1 level of grouping)  
------------ Group 2 | == = = ==== Layer 2 (2 levels of grouping)  
------------ Group 3 |========= = Layer 2 (2 levels of grouping)
