Hi @David_Pollacchi! 
Thank you fo reaching out!
If I understood correctly you would like to have a task appearing in two different sections of a Project, correct?
If you are referring to subtasks, this is actually possible to achieve. You just need to add the subtask to the desired Project and section (using the Tab+P shortcut) and it will be shown both in your task list under the section chosen and as a subtask of the current parent task.
Would this help David?
