I'm not sure what you mean by application layer. You can create a scan request packet just like you create an advertising packet and put any data in it as long as the stack can encode it properly.
Sorry for answering this late, you might have already figured it out.
SCAN_REQ PDU is set completely by softdevice depending on previous settings of scanner device address and the advertiser device address from which scanner wants to get more data.
