compress citation of multiple set members in biblatex

Question

I must admit that I feel a bit stupid at the moment. I am pretty shure that I have seen this on sx already but I don't find it any more since it has been hidden in a comment as far as I remember.

Citing members of a @Set in biblatex with Biber I would like to compress citations similar to normal full entries - see image and MWE below. Going through the biblatex documentation I did not find this point...

Here is what it should look like:

Any input anyone?

MWE:

Cleveland\supercite{fish:drugs:cleveland:use} writes some hard stuff.

Be adviced that after heavy stuff like this\msupercite{Beiglboeck:Koffein,DHS:SMR,set:fish:drugs} you should relax\supercite{A:V2,A:V3,A:V4,A:V6} a bit, were the last citation should look like the hard coded variants\textsuperscript{4b-d,f} or.\textsuperscript{4b-d,4f}
