Switch to simple mode on the players tab, (Players Tab>Track Players>Simple Mode) you can use this mode in the way you suggest, which you can maintain the screen information (Entries, Players, Average Stack, Chips in Play, Tables etc etc) this method does not track players names etc, if you want you can switch to simple mode after registration if you wish to do a seating draw, or can start straight away in simple mode.
I found the best way to operate in simple mode is by checking the "Increment by one in simple mode" option in Preferences>Behaviour
