Clearly, it is possible to have tasks in a plan be prerequisties of tasks which precede them in the layout.

Currently the only way I can create those in Plan is to reverse the order of the tasks, create the dependencies and move them back. In MS Project you just input into the dependencies list the numbers of the dependecies and prerequisites directly.

Am I missing something? Is there a way to do this or a rationale for not doing it?
