@saadkhalil-rs can you confirm, if this still requires work, or if we already have this functionality

No, I rechecked incr and repeat with different scenarios both of them are working. Was not able to incorporate a region by using both incr and repeat together. Actually VTR documentation also does not use them together, so do not need that functionality.
