GPIB Adress Setup VI for several Instruments

Hello,

I'm trying to setup 5 different measurement instruments for a project. What I want to do is to have a VI where I can select the GPIB adress for each of the instruments. 

Those adresses should be 'saved' so I can use my instruments for different measurements later. 

What is the best way to do this and how can I make a interface from this VI to other VI's.

Thanks!
