Request - use a sticky card as a flowchart object

When I am designing a business / data workflow, I like to use a flowchart.
In many cases, I would like to be able to drill down on some of the items within that flowchart.

The sticky card would be a great object that would allow drilling down to further detail.
I can sort of do it now, but it requires adding connections manually.

Another way would be to allow links on Flowchart objects - links to either another board, a website or a google doc.
