Flatten Today - Enabled Permanently

It would be very useful to add the functionality to set the Flatten Today Time once and every day it will exit positions at the market close or whatever time you set it to. Right now, I would have to set the new Fatten Day time and enable it over and over every single day, which is a very big hassle and I will probably forget to do it. Plus if its a setting on the account, I will not want to play with it, whereas now I have to manually set it every single day. Please add this feature.
