"Select ALL" runners on your charts - and the ability to turn it ON ALL as a default

On your chart settings i always need to hit the button “SELECT ALL” if there are more than 6 runners in a race.
I Would love to have, on my settings page presumably, the ability to have the setting of ALL RUNNERS ALWAYS selected.
i dont see the need to see just the first 6 runners in the market - it assumes the other runners dont matter if you are looking at the chart ?
thanks
