How to retain comments provided in dynamic participant step : AEM 6.2 classic UI

Hi All,

We have a workflow being developed in AEM 6.2 classic UI. Right after "Flow Start", there is a dynamic participant step say "A", there is an OR split and 4 branches/flows under it.

1] In one of the flows, after "A" we immediately have two custom process steps in succession followed by a dynamic participant step say "B". If we give some comments in "A" step they are not carried over till it reaches "B".

However,

2] In the same sub-flow #1[mentioned above] if I have a custom process step and then a dynamic participant step say "C", then comments given in "A" show up in "C".

But our requirement will need to have two custom process steps in succession.

3]How do we still retain the comments provided in our scenario. Any thoughts/pointers/reference code on this will be really helpful.
