Hello Zeakiller,
Two ways:
1 - Make current values default, you can only do that if the vi it's not running. You can see the Evan's answer in the following link.

2 - You can save current values when exiting and when you open the application, you have to read them.
You can use the vi's method to get all controls and indicators values, using method "control value".
