How do I set a default Shell Status value in a Project/Shell creator BP?

How do I set a default "Shell Status" in a Project/Shell creator BP?

Currently we have 4 values for uuu_shell_status

• Active
• View-Only
• On-Hold
• Inactive

However it appears to be a system element and thus I don't know how to:

1) Edit the list of values

2) Set which value should appear as the default. (We would like to set it as Active)

I suppose one alternative could be to set it such that the default status of newly created Project Shells via our "Project Request"  to Active but I don't know how to set the default value on the Pull Down.
