Multiple field resolver same data loader

[gilteplitsky]

Hi,
If I have a schema like this:

MyObject {
field1
field2
field3
field4
}
(It is actually more complex with bigger hierarchy)

data for field 1 + 2 and 3 + 4 are coming from different sources.
I am trying to create data fetchers for field 3 and field 4.
Is there a way to use the same data loader for both?

the data fetcher should return a specific type but as loading those 2 fields is actually returning an object, I can't return it from the data loader.
