Support for building tree in externabl tables via hook_views_data

Good afternoon, a very convenient module in terms of building a hierarchy of strings, I successfully use it, but there was one difficulty:
There are certain sections of the site that output information from external tables, by hook_views_data
Among such tables, there are hierarchical structures, for example:

id; title; parent_id

That is, the string refers to itself to build the hierarchy.

Is it possible to add something to the existing ones:

• Taxonomy (in core) - parent/child relationships
• References - node and user references
• Relation - references between any entities (D7 only)
• Entity reference - references between any entities (D7 only)
• Organic Groups (D7 only)

- the ability to specify a specific field that points to the parent of the record
