BBT Default and Glow Genius Options

Is it possible that the 'default' BBT be set to N/A? When I am looking at my chart for BBT and there is a day I forgot to take my temperature it shows me at 98.2 which is rarely correct and throws off the ebb and flow. 
​Also, is there  a way to choose what is on my Glow Genius? Ever since I had the option for trying to avoid pregnancy it changed from showing me my BBt and now shows weight which I don't take everyday. 
​Thanks.
