Yes, and it is one step less than what you describe. Slew the telescope to
an object.

Take an image and notice where the center of the image is.

Then click on that location in Guide.(in other words center Guide on the
image)

Now click on the "Add Alignment star" box on the Scope Pad.

The telescope will now be aligned on that location. You can now center
your target by clicking on it in Guide and then clicking on the "Slew
Scope" button on the scope pad.. The scope will make a small move to
center your target on the CCD. This saves the process of guessing how far
to move the scope to get the image centered on the CCD and taking a second
or third image.

Good observing,
