That’s one way to do it, but may get tedious as you get more observations. I use the “Similar Observation Set” field as described by @kiwifergus here: https://forum.inaturalist.org/t/using-the-field-similar-observation-set-for-linking-observations-of-lepidoptera-when-raising-on/1018
Then you can post a link to the search page that will bring up all of your linked observations: https://www.inaturalist.org/observations?verifiable=any&place_id=any&field:Similar%20observation%20set=25116939
Which is cool.
