Change CurrAsm selected within JobEntry

How can I have a JobEntry Customization open with a specified Assembly selected as the Current Asm? I would also like to prevent the user from selecting any other Assemblies after the form is opened

We may need the actual business need to know how to best guide you.
However, you can find the row number of the Assembly you wish to select and set the EpiDataView’s Row property. Then, hide everything that could allow the user to change to a different Assembly.

But, I would offer that a Dashboard would be better in this case. Then you can show specific details and not have a huge customization.
