Hi!
Yes, there is a way.
What you could do is use a String.Format expression. This way you can show multiple variables on the dynamic text.
On your case something like:
String.Format("{0}: {1} {2}{3}: {4}", "Material Costs", MyModelEntity.MaterialCosts, String.NewLine, "ProductionCosts", MyModelEntity.ProductionCosts) should work.
As a plus, you could use a state to disable/enable these labels with a button and a process. Something like:
Math.If(EnableTxT, String.Format("{0}: {1} {2}{3}: {4}", "State1", ModelEntity.State1, String.NewLine, "State2", ModelEntity.State2), "")
