How to show only certain custom step types in run time

[Chickentree]

I am using the TestStand API in my LabVIEW GUI. This is what I want to do.

1. The user launches a splash screen VI where they can select the test type.

2. Depending on the selected test type, the GUI only shows the appropriate custom step types in the palette.

Is there any way to do this? Any tips will be appreciated!

Using TSENV files seems to be the answer.
