Planning Release and working with the Products

[Alpa82]

Dear community,
I would like to clarify few details about creation of release and planning the scope
1) If I understood correctly, from the Release planning I can create a new release record only if I have Version.
i.e.: for each product we would like to release version needs to be created.

2) creation of Features - is using Features or optional?
scenario: DPR will not be integrated with JIRA to import any features or Epics.

3) Can I add arefacts from Epic/User stories from the Agile Development 2.0 to the Release planning?
I see in the documentation  managing data from external tools but did not find information how to add artefacts and check data within the SN.
4) As per the documentation there should be a system property: ' - Create a release with a wizard (servicenow.com)

The number of Included products that can be added to a release depends on the system property sn_dpr.multi_product.included_products_limit. A release admin can update the value of this property to increase or decrease the limit in the SN Docs site.' Manage product hierarchy using Included products' (servicenow.com) 
I cannot see such property in our demo instance, could you please advise?
Could you please provide some examples/scenario for using the product hierarchy?

Thank you very much
