Backing up Multimedia with archivist

Hi, many thanks for Archivist which is very convenient
Would it be possible to choose from the config file whiwh hooks to use for the ynh core ? And especially the data_multimedia, because I want to back it up and it is excluded in
The best would be to make a separate backup, because data_multimedia doesn’t change as often as the rest of the core, so it shouldn’t be backed up as often.
Thanks in advance !
