Printing an additional label based on a condition in VTL

Question

Hi guys , I have a doubt regarding VTL labels and if the below can be done and if yes, how -

I have a general label which goes on like

^XA
....
//calls a macro//
//Based on reply from macro #parse(another zpl file to be printed as an additional label after the current zpl file is printed  )
...
^XZ

So, based on the reply it parses and prints another zpl file to produce a label, in addition to the one that it is currently printing. Is this possible? Does it have something like parsing the second zpl after the ^XZ ? Also the zpl that is parsed under condition, lies in a different directory than the one that is currently being parsed.

Any pointers with regard to this would be of great help.
