When updating a custom step type, user inserted values for this step type are overwritten.

[CristianL.]

I have a .dll with different functions inside. Each function with its own set of parameters.

I create a custom step type for each function. When using the custom step types the user specifies in the pre expression the values of the parameters to be passed to the module.

The problem is tha when I update the custom step type (adding a new parameter for example), and I select "Update all steps in sequences", all the pre expressions will change to the new values from the step type, overwriting the values entered by the user.

How can I prevent this?

I would like to be able to modify the custom step type, but to retain the values the user entered, (and the user will review the steps manually)

Any other solution (not using pre expressions) would also be acceptable.

Below some pictures of my tool chain.

I create a custom step type with the module taking the value from an intermediate IFC container (Created in the Custom Step).

User inserts the step type in his sequence and modifies in the pre expression the value to be passed to the module.
