Hello, 
I have two reference clusters that are strict type def. and I need to merge them into one but keeping the Labels of the objects. This is just an example because I have a larger code with several objects and I need to merge references clusters into one, since many SubVIs have unbundle by name functions already setted. It is a long story. LOL 
I don't need to have it happening on run time, it can be done before allowing me to create one single reference cluster that I will feed to my unbundle functions into the SubVIs. 
Find below a picture showing what I want to achieve. 
Thanks.
