Does anyone make a 20 Amp GFIC Recptacle with 30 Amp pass thru?

Does anyone make a 20 Amp GFIC Recptacle with 30 Amp pass thru?
If not, what are the problems with a 20 Amp GFIC Recptacle with downline recptacles that draw a combined 30 Amps. (This is on a 30 amp circuit with #10 wire).
Thanks

The problem is that if you have something like an extension cord plugged into one of those outlets and there is a short, the breaker may not shut off! The wire will get red hot. Your house will burn down!
For example the heating element on an electric range gets red hot and that is like a short (heating element), but the high amperage breaker used for a range sees that as a "normal load".
Best to have multiple 20 amp circuits each with their own 20 amp breaker.
