[JPD Premium] How to filter a board by a linked idea

[Zaar Hai]

My idea tree is Initiative -> Opportunity -> Solution -> Experiment.

I'd like to have a dedicated board for each Initiative as follows:

1. Card fields: Solutions + its Experiments
2. Group by: Opportunity
3. Columns: Status
4. Filter the board to only Opportunities/Solutions/Experiments belonging to a single Initiative

My struggle is with 4 - JPD doesn't understand transitive connectivity. Even if I link not just an Opportunity to the Initiative, but also all the Opportunity's Solutions, it would filter the cards, but not the Group By rows - the latter will still show all Opportunities rows, even from other Initiatives (hiding empty rows is very confusing since it also hides empty opportunities from the current initiative).

Have you considered supporting transitive connections in filters?

Or any other solution you can suggest?
