I have two round Directv dishes, dual LNBs from 101, 110, 119 and I want to combine for input in the WB68 multi-switch.
Is this possible?
I'd like to connect a DVR and 2 Standard receivers in the back end.

The round dish can't receive from more than one satellite. Now if all you want is 101 and 119 then connect the dish aimed at 101 to the Sat A (13/18v 0 Hz) inputs and the other dish to the Sat B (13/18v/ 22kHz) inputs.

You can add more LNB to a round dish. There are even solutions for it such as the "magic bracket"

*shrugs* or even use a Dish 500 with Direct LNBs to get the 110/119...and a 2nd, round, dish for the 101
