I have reattached the file with Overlay sheets for:

1. Normal use case - Match First use Left side/Discard Ref Row Right Side
2. Duplicate Ref Rows Left Side/Discard Ref Row Right Side
3. Concatenate with delim ; Left side/Discard Ref Row Right Side
4. Concatenate with line break Left side/Discard Ref Row Right side

Either right or left option to Do not create overlay will result in the overlay sheet not be created
The right option to Copy Control ID from Ref will result in an overlay has all REF rows (resulting file is too large to attach).

The YoPauli in the RS_SHEET is what creates the Do Not Create Overlay Cancel with the Left bottom option buttong
The YoAdrian in the NDS_SHeet is what creates the Do Not Create Overlay Cancel with the Right option button.
