Yes. An easy method to do this is by taking a section of the flooring (cut-off) and then placing it next to the door jamb...flat.
Next, lay a sharp handsaw, or Japanese Flush Cut Saw onto it. Side of blade on the floor piece. Cut slow and straight. The result is a nice clean cut, that yur flooring will snuggly slide into.
I believe that you can find Japanese Flush cut-type saws in the Big Home Improvement Stores.
