Way to remove 'since you began investing'?

I have recently decided to use the app to just hold a set of shares in one company for now. When selling some shares to put the money into the one stock some sold for a bit less than what I bought them for.

Obviously when displaying the history of my investments this is included, as I’m not particularly interested in the figure beyond what my existing shares are doing I am wondering if there is a way of having it hidden?
