Backward arrows

Sometimes when I create a flowchart, I want arrows to go backwards, like A<--B instead of B-->A.

The following diagram works well:

flowchart LR
    subgraph A
        1
        2
    end
    subgraph B
        3
        4
    end
    1-->3
    4-->2
    2-->4

flowchart LR
    subgraph A
        1
        2
    end
    subgraph B
        3
        4
    end
    1-->3
    4-->2
    2-->4

But when I remove 2-->4 die diagram looks completely different

flowchart LR
    subgraph A
        1
        2
    end
    subgraph B
        3
        4
    end
    1-->3
    4-->2

flowchart LR
    subgraph A
        1
        2
    end
    subgraph B
        3
        4
    end
    1-->3
    4-->2

If possible, it would be great to have something like

flowchart LR
    subgraph A
        1
        2
    end
    subgraph B
        3
        4
    end
    1-->3
    4<--2

which produces

Despite this: Awesome tool! Love it ❤️

Any news on this? Sounds like a very easy change. ---, --> and <--> already exist, why not <--?

Unfortunately, one cannot simply reverse the nodes, as that completely destroys the layout, eg. when I want 4<--2, I cannot simply write 2-->4.
