How can I make a Simulink block dialog box parameter change dynamically during simulation?

There are a couple of different Simulink blocks where this would be handy, but as a simple example take the Saturation block. Say I have the upper and lower saturation limits set to +/- some constant K in the block's dialog box. I would like to be able to dynamically change K elsewhere in the model. I want the system to behave as if K were a dynamically changing signal input to the Saturation block.

I realize that the Saturation block has very simple logic and that I could fairly easily create the behavior I want with my own subsystem or s-function, but for other applications it is not so simple. For instance, I would also like to have an RMS block (Simscape) which has a dynamically varying fundamental frequency parameter.
