Call Winged Messenger explicitly only works on specially prepared letters, but it’s conceivable that a different Autumn ritual could be devised to send more than just letters.
Opportunities sometimes exist for people to send resources or objects - such as the recent opportunity for any PC to send resources to the Asavean Uprising by emailing PD. Ambassadors sometimes get specific opportunities like this in their briefings each event.
But as far as standard options exist - no, there’s no way to send an object to a distant NPC via magic or similar - at least not in Imperial Lore.
Is it okay to ask what object you wanted to send and to whom?
