  **Transfer the content from the location(s) of multiple filter papers to 1 or multiple tubes.**
  
  This action transfers the content of 1 or more location(s) of multiple Filter Paper to 1 or more tube(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 tube
   
  The example below shows how to make a transfer from "A1" Location 
  of one Filter Paper and "A2" Location of another Filter Paper to multiple tubes:
   
  * from filter paper `11111111-2222-3333-4444-333333333333` "A1" Location
  to tube `11111111-2222-3333-4444-666666666666` and
  from filter paper `11111111-2222-3333-4444-444444444444` "A2" Location
  to tube `11111111-2222-3333-4444-777777777777`
