[Wien] Can Wien2k use with virtual crystal or pseudo atom?

[John]

Hi all,

	I want to calculate many solid solutions, in which at the same
location, two atoms both have their occupancies.  I heared about some
pseudoatom method to build a "pseudo" atom to simulate this kind of
situation.  
     
     Can Wien2k use pseudo atom?  If it can, then how?
