Don't think it's possible. You should make your own dashboard; it's quite easy.
First, get the NetworkTables library. You can build the official C++ and Java libraries using the
project source code (follow readme.md instructions, then add to your project in C++ or Java). There is also
Python,
C#, and
node.js (disclaimer: my own project, used for my webkit smartdashboard)
Then, you can connect to the robot as follows (Java)
Code:
// sets the address to roborio-862-frc.local
// You can also use setIPAddress(String address)
NetworkTable.setTeam(862);
NetworkTable.setClientMode();
NetworkTable.init();
// the table for the WPILib SmartDashboard class
// Preferences and LiveWindow are Preferences and LiveWindow
NetworkTable smartDashboard = NetworkTable.getTable("SmartDashboard");
// the default value parameter is returned from get*() if the client is not connected
double defaultValue = 0;
System.out.println(smartDashboard.getNumber("myNumberVariable", defaultValue));
