I'm wondering if there's a way to include the X and/or Y error bars in the fitting?

Let's say, for example, that I'm measuring something at different voltages. I know my X value has an error bar, and my Y value has an error bar.

To do the error propagation (i.e., to get the correct std deviation and error bars for the slope and intercept) I need to include the errors in the individual points.

Is there a way to do this now and I'm just missing it? I can display the errors in the points, but it doesn't seem to carry through to the fitting.
