Change the UI for the option to add 'Workspace in line' when creating a new parent line.

When adding a new parent line, you can select which workspaces/ lines should be nested underneath it. The UI of this selection can be confusing.

For example, lets say you're creating a new Parent line A and you need to move an existing Parent line B underneath it. You might select Parent Line B and all of its child lines/workspaces in the selection option which will move everything underneath the new parent line A and breaks the original hierarchal structure (disassociating the child workspaces from parent line B). Instead, you should have just selected Parent line B since it would automatically move the child lines/workspaces without breaking the original structure.

It would be helpful to have a warning message or guidance on how the multiple level selection will work.
