I'll paste Pictures of the workflow below. After completing building a job. We have our own Unique Barcode (Code 128) that is specific to that label. The front office puts on a job (Which Generates the barcode) Different Barcodes for each job > we build the label > Put the specific barcode for that job. Our barcodes are for Inventory, and checking purposes. If there is a better way that you can think of to do this let me know. Lets say this is label 1 it would have barcode 1234, If i build lable 2 now it will have a barcode 1235.

If you can presume of the context (meaning teh frame HAS the appropriate label, and barcodes are expected in the specific lcoation) then a script can do it. I was under the impression you were looking at a more UI dynamic solution.
That would be the idea, I let you develop.
var doc = app.activeDocument,
allPageItems = doc.allPageItems,
n = allPageItems.length,
f;
while( n-- ) {
if ( allPageItems.label ="SomeBarCodeNumber" ) {
f = File ( "/some/path/to/barcodes/"+allPageItems.label );
f.exists && allPageItems.place ( f );
}
}
