Yes , you can define your own rule. You need to populate the table of type SWHACTOR with whatever agents you want to maintain . See the below code :
function z_cvwf_dwnam_approver_get.
""Local Interface:
*"  IMPORTING
*"     VALUE(ACT_PLVAR) LIKE  P1208-PLVAR DEFAULT SPACE
*"     VALUE(ACT_ISTAT) LIKE  P1208-ISTAT DEFAULT '1'
*"     VALUE(ACT_BEGDA) LIKE  P1208-BEGDA DEFAULT SY-DATUM
*"     VALUE(ACT_ENDDA) LIKE  P1208-ENDDA DEFAULT SY-DATUM
*"  TABLES
*"      AC_CONTAINER STRUCTURE  SWCONT
*"      ACTOR_TAB STRUCTURE  SWHACTOR
*"  EXCEPTIONS
*"      NO_ACTIVE_PLVAR
*"      OBJTYP_NOT_VALID
*"      NO_ACTOR_FOUND
  data: l_user  like  draw-dwnam, "User
        l_dokar like  draw-dokar, "Document type
        l_doknr like  draw-doknr, "Document number
        l_dokvr like  draw-dokvr, "Document version
        l_doktl like  draw-doktl. "Document part
  data: xausp like ausp.
*Data for AUSPC_V1 selection
  data: xatinn(12) value 'APPROVER',
        xklart like ausp-klart value '017',
        xobjek like ausp-objek.
  include <cntain>.
  swc_get_element ac_container 'DOCUMENT'        l_doknr.
  swc_get_element ac_container 'DOCUMENTPART'    l_doktl.
  swc_get_element ac_container 'DOCUMENTTYPE'    l_dokar.
  swc_get_element ac_container 'DOCUMENTVERSION' l_dokvr.
Create objek from DRAW key fields
  write: l_dokar to xobjek,
         l_doknr to xobjek+3(25),
         l_dokvr to xobjek+28(2),
         l_doktl to xobjek+30(3).
Get Approver number
call function 'CONVERSION_EXIT_ATINN_INPUT'
  exporting
    input        =  xatinn
importing
   output        =  xatinn.
From table AUSP
  clear sy-subrc.
  select single * from  ausp
           into xausp
         where  objek  = xobjek
         and    atinn  = xatinn
         and    klart  = xklart.
Assign ATWRT to USER RESPONSIBLE FOR APPROVAL
  if sy-subrc > 0.
    raise no_actor_found.
  endif.
  actor_tab-otype = 'US'.
  actor_tab-objid = xausp-atwrt.
  append actor_tab.
endfunction.
