EntityID field optional in standard function "Related entity field"

How: add a "not set" option so it becomes optional

Why: when using the standard function you have to select an entity ID which is not at all useful in my case. Currently you can only achieve this with a custom function.

For Who: syndication admins

Impact: saves additional work while a function already exists to achieve it

Additional context:

Ticket 78161: Related entity field function is a standard function.

string entityId: Optional argument. Specifies the id of the entity from which we get the value of the field. If specified, the result will be generated according to the entity id.

I don't want to specify a certain entity ID. I simply want to fetch a field from a related entity and the value it has to return is different for every Item in my work area so I don't want an optional entityID.

How do I do that? By default it selects the first entity ID it finds and I'm not managing to find "not set" or anything similar. That's a big issue as I get the same output for all my Items as it's looking at that selected entity only.
