Welcome to the forum!
For things like this, I have bookmarked identify filters.
You can string together taxa, places, and/or projects as a much more personalized subscription. I ID/review observations as they come in so I always see the newest stuff.
For example:
Certain taxa I have “subscribed” to, but all in one place:
https://www.inaturalist.org/observations/identify?quality_grade=needs_id%2Cresearch%2Ccasual&ident_taxon_id=47777,781361,117617
One taxon from multiple places:
https://www.inaturalist.org/observations/identify?quality_grade=needs_id%2Ccasual%2Cresearch&ident_taxon_id=47584&place_id=14%2C10%2C46%2C7085%2C6%2C8501%2C66394
Observations from projects I want to see:
https://www.inaturalist.org/observations/identify?quality_grade=needs_id%2Cresearch%2Ccasual&project_id=75095%2C61136%2C66484%2C121503%2C9832
