Helium Field Tester - Read out TX RSSI online

The helium field tester is a great tool, but unfortunately I need it most in environments where reception is quite bad and uplinks work a lot better than downlinks.

So, without the ACKs or downlinks arriving, the field tester shows me nothing but “LOST” frames.
Is there a possibility to check the gateway RSSI/SNRs also with the pre-registered field testers or would I need to re-configure with my LNS setup in order to read out these parameters online?
