Bank Acct Legder Entries Edit Field

I need to add a boolean to the Bank Account Ledger Entries Table.

It will do nothing other than tic yes/no.
I don't need to modify anything else nor should I or want to.
I simply want to called it "Reviewed" or something, my new form will only show the entries that are not checked (or Reviewed)

Regular license will not allow regular users to modify this table.
Is there something like the *Edit* codeunits that allow me to enable 1 field for editing. I was thinking of adding a function to CU370.

any better ideas?
