It is posible to intergrate new fields in TCode F-26?

Hello experts,

I have a taunting task to integrate 3 selections fields in the Standard TCode f-26. These fields are in the Standard TCode f-28. These are:

BKPF-BLDAT
BSEG-SGTXT
BSEG-ZUONR

Can any one tell me how achieve this? Is this at all possible?

Thank you for your respond.
