deallocate type variable only one field

Dear all,

I have the following type variable:

  TYPE::tMACROCELLNODE
   INTEGER                                        :: nElem
   INTEGER                                        :: AA
   INTEGER                                        :: IDnode
   INTEGER                                        :: IDmCell
   REAL(KIND=8),ALLOCATABLE,DIMENSION(:)          :: WFX
   REAL(KIND=8),ALLOCATABLE,DIMENSION(:)          :: WFY
   !
   REAL(KIND=8),ALLOCATABLE,DIMENSION(:)          :: WFtime
   REAL(KIND=8),ALLOCATABLE,DIMENSION(:)          :: WFpdf
   !
   REAL                                           :: qs
  ENDTYPE

During my program, I allocate it as:

first of all:

ALLOCATE(MACROCELLNODE(npairs))

and then

DO i.....

       ALLOCATE(MACROCELLNODE(i)%WFX(n))
...
...

My question is:

Is it possible deallocate only one field of it?

for example:

i=10
DEALLOCATE(MACRCELLNODE(i)%WFX(:))

Thank to all of you

Diego
