This shadowed columns, was done automatically , not from the days off section, I need to change it too Friday Saturday.
Because in the days off section, I couldn’t find something that would just shade the columns, like in the picture above
To set the day offs to Friday and Saturday, select these days from the ‘weekday’ field as per the below screenshot.
To shade the column, select the ‘percent 50’ pattern and choose the color shade accordingly.
Please try and let me know if this works for you.
