IF you wanna re-initialise them to a know state, you may wanna try
1) create a property node for each of them, wire the property nodes with prefered value upon re-initialsation.
2) put all the property nodes within a case struction in your while loop with a button control.
With that, you can re-initialise all of them with a single click. With the same method, you will be able to wire them with fixed values upon entering a vi.
Optional
Configuration file can also be created using labVIEW.
Value for each control/ indicator is stored in a file, which the values will be read back and write to each control/ indicator.
have fun
