Can Parameter Updater be used to change Works Process failures?

Hi,

The title says it all. Can Parameter Updater be used to change Works Process failures? And if it is possible, how?

I have a lot of works processes and I would like to use parameter updater as a tool to insert failures on and off. I know how to use parameter updater and managed to change speed of the conveyors for example but now I wonder if Parameter Updater can be used to change failure distributions of works processes.
