Rigidbody.solverIterations equivalent for Rigidbody2D

3D Rigidbody has two properties, solverIterations and solverVelocityIterations, that override the corresponding default iterations specified in the project's Physics settings for that Rigidbody. Rigidbody2D does not appear to have the equivalent properties that would override Velocity Iterations and Position Iterations in the project's Physics 2D settings for that Rigidbody2D.

Is there any way to set different levels of 2D physics iterations for different objects, the way there is for 3D physics? I have a use case for doing this, as I have a chain of objects that needs to be simulated with a high number of iterations while everything else does not need to be. Applying the higher iteration count to everything diminishes performance.

Thank you
