Is it possible to replace an item inside the player's inventory without specifying its location?

I'm trying to create a system when a player make contact with an entity, it will replace a specific item on the player's inventory without specifying its location so for short it will just replace the designated item

You can use /clear along with /give.

You can use has item selector in the give command to test if the player has that item. Then, run the clear command with hasitem selector too.

No, you can use the target selector in the @p of the give and clear command.

Please make sure to add r too so it doesn't runs the command on a player far away if the nearest player doesn't have it.

I mean r (radius) target selector.

I like the "copy that". It's like I'm talking to a aircraft pilot or someone from ISS.
