I wish expression could be put into any field that describes and any element. For example, the capacitor has capacitance field and ESR field. I wish I could put an expression in either or even both fields. And I don't mean simple expressions. I mean full expressions that include other voltages and currents in the circuit. Also, all complex expressions, such as PWL, MAX, EXP, ABS, CSV, etc.

It is only partly what I want. These examples are only static calculations using fixed inputs. I want it to be dynamic. For example, I don't want it just calculating a resistance based upon a target gain. I want to make a resistance based upon a dynamic voltage or current or any combination of multiple voltages and currents that are dynamically changing while I'm simulating. I've used "dynamic" redundantly here for emphasis. Currently, Circuit Lab won't allow it.
