AutoCad 2D :: Dimension Line Gap?

I need to routinely insert text into or near my dimensions but my dimensions need to be kept as basic dimensions meaning they need to have the box around them as in the picture. What I want to do is what the first dimension shows with the "2x" outside the dimension box but that first one is a combination of suppressing the dimension line and inserting a leader so the 2x will be within the line. Otherwise the normal dimension is what is shown below. How can I increase the line gap from the dimension options without 1) increasing the dimension box with DIMGAP or 2) inserting a line that's separate from the dimension itself or 3) exploding
