    Hi,
    1. pin planner doesn't display all available pin option by default. Use "customize columns" in context menu to display "Slow Slew Rate" option.
    2. The tcl command is
    set_instance_assignment -name SLOW_SLEW_RATE ON to <pin name>

    There's no "medium" slew rate setting. You can set "slow slew rate" for individual pins, default setting is off. Review resource section, output pins in fitter report in case of doubt.
