From the Menu Bar: Window->Preferences->Transformation Extender->Map. In the Editor section at the bottom right you can specify "Maximum number of 'From'/'To' cards:" Other WTX IDE configuration settings are set here also. You may have to open and close the map or at least move around the map in order to have the additional input/output cards show up.
I believe these preferences are specific to a workspace and that if you create a new workspace, you will need to reset your chosen preferences.
