Yes, we would love to have this feature, but nobody has built it.

That's partly because testing the ORPort is relatively easy, because the
Tor program speaks the Tor protocol; but testing the obfs4 port is harder,
because the obfs4 server side doesn't usually do client things too.

Here are two tickets to watch:
https://bugs.torproject.org/30477
https://bugs.torproject.org/31874
...or you don't have to watch, you can jump in and help. :)

In the mean time, also check out the "bridge scan" tool that phw put up:
https://bridges.torproject.org/scan/
which is linked from the instructions in e.g.
https://community.torproject.org/relay/setup/bridge/debian-ubuntu/

Thanks,
