Minimum ClientRates in Engine.ini

I want to say this is technically a Installation/Setup deal.

So basically what I want to do is add something that will actually tell the clients the minimums that can be used. The MAX settings are there. Just a couple of games people just need to have their limits raised a bit more and I don’t want to show them how to do it if I can just force it.
Basically I want to change the ClientRate to force the minimum. I randomly tried MinClientRate=xxxx but that didn’t work. Is there something like this in the Engine.ini? All I find is MaxClientRate=xxxx. Thanks!

Shucks. Nobody knows?
