[otrs] Free fields at Free Field (withn the ticket) Adding Note. Close Ticket

Hi all I have created some free text fields, my questions as below :- i) After added a note with free field information for a ticket, if I create another note again, would the same free field information of previous note appear ? if it is the same, if I change the information, does it overwrites the free field information of previous note ? possible to make it not to overwrite ? ii) Likewise for a close ticket.
