When I display a menu with select, tt displays something like this

1) Sample
2) Sample

I would like to turn it into

[01] Sample
[02] Sample

Is this possible?

I'm having trouble editing this part

    clear
    printf "\nCUSTOMIZE WS STATUS\n\n"
}

_msg ()
{
    _title
    printf "\n"
    read -p "Your message : " message
}

_color ()
{
    _title
    printf "\nChoose color:\n\n"
    select option in blue red green;
    do
            if [[ -n ${REPLY//[0-9]/} ]] || [[ $REPLY -lt 1 ]] || [[ $REPLY -gt 13 ]]; then
                    printf "\nTry Again.\n" && sleep 2
            else
                    color=$option && printf "\nSelected Color: %s\n\n" "$color"
                    break

Can I modify how select numbers its menu items?
