How do I make it where if i am overlapping 2 objects it can only grab 1 of them instead of both of t

I have a character who is able to grab enemy and use them as a shield or can throw them at a enemy but some time when the character is overlapping 2 or more it grab them all how do i have them interact with only one of them instead of both of them

Add an extra condition like 'pick nearest to character'
