Filtergraph~ Multiple Filters, Parameter output

I would like to create a multiple filter filtergraph~ that i can tweak each filters using knobs\number boxes.
But also being able to use the mouse by dragging the bandwidth regions.
When tweaking using the mouse, i would like to update the knobs values using the outputted values of the filter.

The issue is, the filtergraph~ only seems to output the values of the last filter.
Is there a way to change which filter gets his values outputted from the object?

Heres an example patch, when moving the first filter using the bandwidth regions, the filter values (q, freq, gain) does not get outputted.

Could this be a bug?
Cause the refpage says this about the seventh outlet:
Filter number. Indicates which of the cascaded biquad filters is being highlighted and/or edited.

And no matter which filter i’m editing, its always the last filter number that gets outputted.

but it works only from filtergraph, not with your knobs. Not sure why it outputs different data.

Thanks AFWI!

for the knobs issue, if i use the params message and send all knobs parameters in one it works.
