Use @IndexedEmbedded for indexing only the first element of a list

I have a terrible problem due to a high volume of data on children of my masters. I have 2 cases. 1st case a master object with a list that has 1000 records and 2nd case a master with a list that has one record. I would like to be able to do indexing dependency only for the second case. I thought of applying transient object as well, but again here it applies index to all the details.

    @OneToMany(mappedBy = "field", cascade = CascadeType.ALL, fetch = FetchType.LAZY, orphanRemoval = true)
	@IndexedEmbedded(structure = ObjectStructure.NESTED, includePaths = {"id"})
	@IndexingDependency(reindexOnUpdate = ReindexOnUpdate.SHALLOW)
	private List<Object> list = new ArrayList<>();
    
    ....

    @Transient
	@IndexingDependency(derivedFrom = {
			@ObjectPath(@PropertyValue(propertyName = "list"))
	}, reindexOnUpdate = ReindexOnUpdate.SHALLOW)
	@IndexedEmbedded(includePaths = {"id")
	private Object object;
	
	public Object getObject () {
		if (CollectionUtils.isNotNullOrEmpty(list)) {
			return list.get(0);
		}
		return null;
	}
