How to add components to selection screen generated from logical database ADA?

Hey gurus,

I have a program using logical database ADA, which have the following selection screen generated automatically because of this code

TABLES: anla0,

         anlb,

         anlav,

         v_anepk,

         bkpf,

         anlz,

         anlcv,

         cdhdr,

         cdpos,

         dd03l,

         dd04t,

         anep,

         tabwt.

I would like to populate this selection screen with my own components where the red line is. Is it somehow possible to do it thru the code? If I make some parameters it is added to the bottom of the screen but I need to put it where the red line is.
Or the only option here is the screen painter?

Regards,
Robert
