  +**Transfer the content from multiple filter papers to 1 or more wells.**
  +
  +This action transfers the content of 1 or more Filter Paper to 1 or more well(s).
   The action takes an array, which contains the elements of the transfer(s).
    
   * `source_uuid` uuid of the source Filter Paper
  -* `source_location` is the location on the Filter Paper (like "A1") from transfer the aliquots
   * `target_uuid` uuid of the target plate
   * `target_location` is the target Location (like "A1") to transfer the aliquots.
    
   The example below shows how to make a transfer from two Filter Paper to 2 plates:
    
  -* from filter paper `11111111-2222-3333-4444-333333333333` "A1" Location
  -to plate's (`11111111-2222-3333-4444-666666666666`) "A1" well and
  -from filter paper `11111111-2222-3333-4444-444444444444` "A2" Location
  -to plates's `11111111-2222-3333-4444-777777777777`  "A2" well.
