This feature used to be available in Illuminations, but now it is not.
In my time programming systems, we have only used this feature a few times. We are not looking to disable a system. We just need a way to protect our work until final payment is made on our contract. Right now I have a client which we have finished programming and have even serviced in good faith. Problem turned out to be breakers going out and knocking down parts of the system. However, we not been paid according to the stipulations of our contract. If they want, someone else could be hired to come in and extract and modify our program making it possibly economical to not pay us.
I would like to see this feature added.
