Technical Lineage Tab for Custom BI Report Asset Type

Is there a way to enable the Technical Lineage tab for custom BI Report Asset types? For example, we are building custom technical lineage for Oracle BI Reports (asset type that does not come OOTB) and we'd like to have this lineage viewable from the Oracle BI Report asset page instead of navigating to the asset pages of the underlying tables and checking the lineage there. Has anyone done anything similar or knows any other workaround? 

The collibra documentation says the following: The technical lineage viewer shows the technical lineage and allows you to edit the view. You can access the technical lineage viewer via the Technical lineage tab on Column and Table asset pages and BI assets of the same level. But what does BI assets of the same level mean?
