To have multiple copies running in the way that you describe, you'll probably want to take a look at something like this: 

Asynchronously Calling VIs 

Asynchronously Calling Multiple Instances of a VI for Parallel Execution 

There are 3 examples in the built-in LabVIEW Examples Finder, that you can find by opening the Detailed Help for the Start Asynchronous Call VI (link in context help, or right click on and choose Help). These show some different behaviours.

A good example is also provided by Hoovahh here: Building an executable with .vits with LabVIEW 2011 (ignore the forum post title, the example linked to is good).

Can you Clarify your Question?

1.Do you want to display calling VI (Referenced vi) in the same Caller/Main VI?

2.OR Do you want to call the Same Referenced VI Multiple Times based on user action?

Check for reentrancy execution.

You can find examples in NI Example Finder "Reentrant VI Execution"

You might also find the answers you need in my first post (#2 in this thread).

I'd like to suggest again running the example in the 3rd link and please let us know if it's close to what you need.

To run them at "clickable" times, simply open the reference as needed and call each time (as in the linked example).
