How to know CECOs and Accounts that have in different forms

Hello Experts, I have an assignment to do,

in planning process we have all the accounts and all de cecos covered by different forms.

I have maybe 50 forms with different parents of Cecos and different Accounts (different combinations) because is divided by different users/security.

I would like to know if is possible to know if some account or some ceco is not covered in one of the 50 forms that I have, because during the closing we have to create new accounts and cecos and maybe administration don't update the correct form for new cecos or accounts.

Is there any function (groovy, attribute, udas) that with a "administration form" knows about which cecos or accounts are not covered in these 50 forms?
