If you don't name individual ships (or even if you do but know which names match which ships) you can use the planet list to do this. Open the planet sidebar (furthest left button on bottom of main display, next to the research tab). At the top of that sidebar there is a button to switch between the planet list and the ship list. There you go, a list of all your ships and fleets in neat alphabetical order, with some other sorting options if you want. Scroll down the list and find the ships you're interested in, and click on the ship picture. The map will automatically center on the ship you select.

Admittedly, your idea is probably faster. But you can still do it this way if you need to.
