Grouping subscriptions of instances that share the same name/topic - Lemmy.World

Don’t know if this is possible and possibly would be better if it was implemented from Lemmy/the Fediverse itself, but would it be possible to group subscriptions of different instances that share the same topic? For example, I am subscribed to Asklemmy on both lemmy.world and lemmy.ml [http://lemmy.ml] and have to browse each individually even if they share the same topic. Sorry if I didn’t grasp how it works correctly, am still trying to discorver how the Fediverse works
