How to display multiple formsets in one another?

On the Site Form is used to give data to a case but since there can be multiple on a site it is made as a formset. In addition, each case can have multiple m2m relations, which are also a formset. The second formset therefore can be used for each of the first formsets.

But how to GET and POST data there? Can prefixes made dynamically or is there a whole other way around?

My current approach is to have both formsets as such but have the second one with an iterated prefix.

view.py

def rezept_lookup(request, my_id):
    b = Auftrag.objects.filter(id=my_id).first().messung_auftrag.all().count()
    
    InhaltFormSet = formset_factory(InhaltForm, extra=5)
    FormulierungFormSet = formset_factory(FormulierungForm, extra=0)


    q = Auftrag.objects.filter(id=my_id).first().messung_auftrag.all()
    b = [x.messung_rezept for x in q]

    formset = FormulierungFormSet(request.POST or None, prefix="rezept", initial=[{'bindemittel_name': x.bindemittel_name,
                                                                 'messung_id': x.messung_id,  
                                                                 'bindemittel_menge': x.bindemittel_menge, 
                                                                 'untergrund_name': x.untergrund_name,
                                                                 'schichtdicke': x.schichtdicke,
                                                                 'isActive': x.isActive,
                                                                 'rezept_name': x.rezept_name } for x in b]) 
    formset_inline = InhaltFormSet(request.POST or None, prefix=[f"inhalt_{n}" for n in range(0,5,1)]) 

    
    if request.method == "POST":
        if formset.is_valid():
            for form in formset:
                temp = form.save(commit=False)
                temp.save()
    
    context = {
        "formset":formset,
        "formset_inline":formset_inline,
    }

    return render(request, "template.html", context)
