Thanks for chiming in and correcting me, a quick look at the SDFC shows that apparently things have changed
And it looks, based on the T&C's of standby, that the number of connections aren't allowed to be changed there, either. I suppose YMMV depending on availability on the flights and the agent you talk to. But be very respectful and know that you're asking for an exception when asking - don't demand it.
I can confirm that I was able to do this via the standby method in an AC in November. But I was denied it at a different AC (pre-merger US club) on the same trip.
