Screen enhancement for FI12 T-Code

Hello Experts,

Hope all are doing great..

We have a requirement to add a new field in FI12 T-Code(Bank Accounts - Bank Account Data Section)

I have tried in all the possible ways to find screen-exit but could not able to get the enhancements.

Please suggest me whether this requirement is possible, if so please let me know the exit names.

Thanks in Advance..
