Ms Access SQL - Update using 1 to Many relationship

Can someone tell me how I would update my records in one table where the ID I am joining on appears multiple times in its corresponding realtionship table. The query I am using is;

UPDATE tbl_Artemis
INNER JOIN tbl_Unique_SPN_Trades ON tbl_Artemis.[Client SPN Number] = tbl_Unique_SPN_Trades.spn_id
SET tbl_Unique_SPN_Trades.[Sales Person] = [tbl_Artemis].[Person Name], tbl_Unique_SPN_Trades.Team = [tbl_Artemis].[Team Name - Level 1]
WHERE (((tbl_Unique_SPN_Trades.[Exclusion Type])=0));

Problem is SPN appears quite a few times in one table but I only really want to say update table, where ID's match but group by SPN in the second table so i only see the last entry under that ID?

I hope this makes sense?
