[Koha] Logging action_logs when merging records

Hey all, Recently I noticed that no action_logs are created when merging biblio records together, I was expecting to have in the action_logs all the actions that were made, but nothing is logged as opposed to a regular edit or delete, for example. I was wondered if this is intentional, there's a way to enable it or the feature is just missing. Thanks a bunch, Pedro Amorim
