Query on items with multiple linked_items

If I am not mistaken, I don’t think there is a way to query items so it returns linked_items of multiple columns in a single query.

For exemple, I have a board (A) that has 2 connected columns (B & C). Right now, I make a first request that retrieves items column_values of board (A) of which I am extracting the pulseIds of board (B) & (C). Then I make 2 request to retrieves items column_values for both (B) & (C).

The linked_items fields on a Items query is great but it can only be done with one connected column.

Yes, I could reduce the number of queries to 2 instead of 3, if I include the query on B or C in the linked_items field but, in my opinion, it complexify maintenance and is hard to document.

If there is a way of doing it, I would be glad to hear it!

Thanks!
