Yes. It is possible. Please refer to bullet e) in Section 5.5.3 of RFC4862 on RA processing which states "If the advertised prefix is equal to the prefix of an address configured by stateless autoconfiguration in the list, the preferred lifetime of the address is reset to the Preferred Lifetime in the received advertisement." This should give you the effect you are looking for.
