Manta Data Dictionary, Hierarchy, Path for RDBMS semi-structured(JSON, BLOB & CLOB) Columns

Problem :
Currently Manta Data Dictionary, Hierarchy, Path doesn't capture the RDBMS data dictionary beyond column level. There are multiple system which save the JSON/BLOB/CLOB into RDBMS columns. Need to have a way to represent the JSON/BLOB/CLOB columns in Manta Flow for DD & DL

Steps to reproduce : 
1. Have a table-column saved with JSON/BLOB/CLOB data structure in a RDBMS Data Store like Oracle/PostgresSQL/etc
2. tried to use Manta OTB Scanner to scan for DB
3. Open Manta Flow to view the DD & DL
4. The RDBMS columns don't get represented for JSON/BLOB/CLOB data

Suggestions/Answers you seek:
Understand the RDBMS Database/DDL is not aware of the structure of the data stored in the RDBMS semi-structured data(JSON/BLOB/CLOB) columns. And it can't be automatically captured from DB using the Out of Box Scanner.

If we can get the structure by other means and potentially inject the nested DD with open Manta files process. 

1. Is there a capability in Manta, that is available or planned to go beyond the standard structure for these kind of nested semi-structured data in RDBMS to define the Data Dictionary (& use it for Data Lineage) with out impacting the RDBMS Structure and Subsequent processes
2. If not, in the short term. What is your recommendation to represent these nested semi-structured data for RDBMS JSON/BLOB/CLOB columns Data Dictionary (Technology /Hierarchy /Path) & Lineage in Manta
