Reference returned values in later queries ?

[Angahran]

Graphiql newbie here so please forgive me if this is something obvious.

Is it possible to run a graphiql query and have fields returned by that query available to later queries ?

e.g.
query searchByPhone takes a phone number and returns a firstname and lastname.
query searchByName takes a firstname and a lastname and returns a street address.

Would it be possible to simply provide a phone number and have searchByName use the firsname and lastname returned by searchByPhone ?
