Thank you for the reply. I apologize though, I am a newbie. I am currently using legacy forms, will using content controls muddy up my form and possibly cause issues when users try to fill out this form? This form will be distributed to my team and they will use this when they need it.

Edit: I just realized that I left out a piece of information that may change your answer. I want to lock this fillable form so that the user cannot modify anything other than the fields and dropdowns I have provided. So they would need to be able add tables either by clicking the quantity of tables in a dropdown or if they could have access to a button such as + or add, that would work too.
