Using two gateways for single deive

Hello everyone,
If i am using two gateways for one device then i am recieving data on both gateways but on things network i am recieving data from that gateway for which i am getting better RSSI.
If i want to recieve data from both the gateways. Is there any way or we can recieve from one gateway only.

If both gateways are connected to TTN and receive the uplink and both use a fast internet connection you will get a single uplink in your application with in the metadata the information on both gateways like gateway ID, rssi, snr etc.
You will never get two individual uplink packets in your application.
