Save Multiple/all Instruments From An Rns File At Once


I created an RNS some time ago, with say 20 instruments (2 vsti, 10 samples, 8 xm instruments).
How can i save them to Renoise Instrument Format easily without having to select them one by one, press save, type a filename (wich does not autogenerate from the instrument list!?) and so forth.

here has to be an easy way, maybe there is a great sampleripper for XRNS files, ok that is nice, but i seek something like that for all types of instrument (the vsti with it’s active preset for instance).
Is there a way? :unsure:
