iPlug2 version of "IKnobMultiControlText" from iPlug1?

Is there an iPlug2 equivalent of “IKnobMultiControlText” that was a common yet custom control in iPlug1? It’s a bitmap knob control with text value display and entry. I am trying to convert from iPlug1 and that custom code is unrecognized in iPlug2.

Something similar…

class IKnobMultiControlText : public IKnobControlBase, public IBitmapBase
{
private:
  IRECT mTextRECT, mImgRECT;
  
public:
  IKnobMultiControlText(const IRECT& rect, int paramIdx, const IBitmap& bitmap, const IText& text)
    : IKnobControlBase(rect, paramIdx)
    , IBitmapBase(bitmap)
  {
    SetText(text);
    mRECT = rect;
    mTextRECT = IRECT(mRECT.L, mRECT.B-20, mRECT.R, mRECT.B);
    mImgRECT = IRECT(mRECT.L, mRECT.T, mBitmap);
    mDisablePrompt = false;
  }

  void Draw(IGraphics& g) override
  {
    int i = 1 + int(0.5 + GetValue() * (double) (mBitmap.N() - 1));
    i = Clip(i, 1, mBitmap.N());
    g.DrawBitmap(mBitmap, mImgRECT, i, &mBlend);

    WDL_String disp;
    GetParam()->GetDisplay(disp);

    if (disp.GetLength())
      g.DrawText(mText, disp.Get(), mTextRECT);
  }
};

IPlugEffect::IPlugEffect(const InstanceInfo& info)
: Plugin(info, MakeConfig(kNumParams, kNumPresets))
{
  GetParam(kGain)->InitDouble("Gain", 0., 0., 100.0, 0.01, "%");

#if IPLUG_EDITOR // http://bit.ly/2S64BDd
  mMakeGraphicsFunc = [&]() {
    return MakeGraphics(*this, PLUG_WIDTH, PLUG_HEIGHT, PLUG_FPS, GetScaleForScreen(PLUG_WIDTH, PLUG_HEIGHT));
  };
  
  mLayoutFunc = [&](IGraphics* pGraphics) {
    pGraphics->AttachCornerResizer(EUIResizerMode::Scale, false);
    pGraphics->AttachPanelBackground(COLOR_GRAY);
    pGraphics->LoadFont("Roboto-Regular", ROBOTO_FN);
    const IRECT b = pGraphics->GetBounds();
    pGraphics->AttachControl(new IKnobMultiControlText(b.GetCentredInside(48, 68), kGain, pGraphics->LoadBitmap("knob.png", 60), IText(10)));
  };
#endif
}```

Will try it. Thank you.
