[Suggestion] [To be discussed]

As far as I recall the API has some advantages that we can use, adding here some points for discussion:

• Endpoints allows both OrgUnit or OrgUnitGroup selection
• Usage might require an ALL rule for period and/or orgUnit
• I believe CO page will not be an ObjectsTable since we do not support disaggregation and it is done per dataElement. I would consider something like the greyed fields page on mantainance for that step.
• Would it make sense to allow filtering on DE page by dataset?

Even though not related to the sync rule specifically:

• Would it be useful to add preview contextual action that compares origin with destination and previews the data/metadata to be imported?
