Counting STEPS in a walk


hi everyone, yesterday afternoon I set a "walk" on my 255. When I started the walk I had already done 2350 steps since the morning. However, I wanted to know the steps related to the walk I was about to start and therefore I thought of adding a data field to the screen that appears during the walk, with the number of steps, and it worked, at the end of the walk I had read 6780 steps. Once the walk was finished, I saved the activity. Later, wanting to check it again, I went to HISTORY, select it, but the number of steps 6780 was not indicated anywhere, therefore the information was lost.
Is it possible to insert the number of steps in the summary that comes out of the upload to HISTORY?
Is it possible to customize the summary screens of the activity uploaded to HISTORY, adding other screens?
Thanks
