How to center text on specific character position?

I have a string with text and I want to output it centering on specific character position.

Is there a way to do so using, for example, label?

Or should I better consider drawing a string using GDI+ measuring each character length and then manually drawing it where I need, centered?

Example, to be clearer:

String: "Lorem Ipsum", Position: 2.

From this, I need the string displayed in such way that character "r" will be in the middle of whatever display box (label, etc.).

Here is a positioning function that should help:

void positionTo(Label lbl, Panel pan, int pos)
{
    SizeF sz0, sz1, sz2;
    sz0 = sz1 = sz2 = Size.Empty;
    using (Graphics g = lbl.CreateGraphics())
    {
        StringFormat sf = StringFormat.GenericTypographic;
        sz0 = g.MeasureString(lbl.Text, lbl.Font, pan.Width, sf);
        sz1 = g.MeasureString(lbl.Text.Substring(0, pos), lbl.Font, pan.Width, sf);
        sz2 = g.MeasureString(lbl.Text.Substring(pos), lbl.Font, pan.Width, sf);
    }
    lbl.Left = (int)(pan.Width / 2 - sz1.Width);
}

enter image description here

Note that I use only the left part measurement. One could use both to refine the centering..
