Automatically assigning a row to a parent line once an intake form is filled

I would love it if there was a way for a row that is entered from an intake form to automatically categorize to a parent line and have the option to place it at the top or bottom of the children. For example, if I have a ticket request form and on the sheet there are 3 parents, Pending, New, and Closed requests. When someone fills in the ticket request form associated with the sheet, the new row would automatically categorize as a child row in the appropriate parent category. In this case New. Having to move manually and constantly move rows creates a lot of manual work. Perhaps a hidden auto-selection on the form settings or the form fields.
