Add custom record at level 2 in Fluid Job Data

Hi All:

PS VERSION - 8.59, IMAGE 41

PS Tools - 8.59.9

We have custom record at level 2 in Classic Job Data , trying to include in Fluid Job data, following the steps in Job Data Modernization Red Paper.

Custom Subpage created with custom record to include at Level 2 but only scroll level 1 can be added in SBF page.

Does anyone have experience adding custom record at Level 2 in Custom SBF and configured using Drop zone? How to check in JOB_DATA_FL component , custom record level ?

Thanks.
