Add field to the transaction variant OT43

Question

Hello,
I found the following Note: 2596 but  I can't create a field in Dynpro:  SAPMF40K /8000/220 and I don't  found other options as badi, user exit, enhancement , bte, etc.
I need to create the following field: FEBMKA-VGEXT_EL on the screens above.
The transaction OT43 by your program uses T021Q table but  I can't modify the table or add an entry T021Q, because internally the  program   that manages the view of fields for transaction FF67, it executes statements as "DYNPRO IMPORT".
Another consideration that the transaction OT43 only "shows possible fields"  and I can add other fields to select and add to the view.
In other words I can select only possible fields proposed Sap to the view,  it works this way ?
Please could you recommend a Note Sap? or perhaps more likely, a copy of the transaction ff67 and modify the new copy of the screen.
What happens to the transaction OT43, if done the copy of the ff67 as zff67?
Waiting for response and very grateful for the suggestions.
The best regards,
Gustavo
