Can you really have the International Star Registry name a star that you can easily see in an amateur telescope, like in A Walk to Remember?

In A Walk to Remember, there is a scene where Landon asks Jamie to look at a star in her telescope, then reveals that he named it after her.

Landon: Can you find this star right here?

Jamie: Sure. [She looks at the map and adjusts the telescope and finds it pretty quickly] So, why am I looking for this star?

Landon: Because I had it named after you. [Shows a rolled up piece of paper] See? It's official. It's from the International Star Registry. [Jamie comes over and excitedly looks at it]

Jamie: It's wonderful. [whispers] I love you.

As he says, it's from the International Star Registry, which despite what Landon says, is not official at all. But since the ISR has been around from 1979, wouldn't the stars that are easily seen with an amateur telescope have been given names ages ago (or even given official names back when telescopes were first used for astronomy)?

_{In researching this question, I found that the original script had Landon instead say "I know it's not an official designation—" and not mention the ISR. Pity that the final version made him seem like he got duped into thinking that the ISR gave official names to stars.}
