Is it possible to change selected dimensions so that they round to the nearest inch?

In a drawing, my document options have units as fractional inches with 1/16 precision.  My dimension properties are fractional.

But sometimes I want to change a specific dimension to round to the nearest inch....I can't seem to make that happen.

For example, I had a linear dimension that came out to 161 7/16in and I just want it to show as 161in.

If I go to change the dimension precision, it only gives me options in decimals and they don't change the fractional dimension.  None, 0.1, 0.01....all keep the dimension at 7/16in.  Changing the linear dimension precision, in options, doesn't have an effect either.

I found that if I edit the document properties and change the units to fractions 2. it will round to the nearest 1/2....but that isn't what I want and it applies to the whole drawing.

I certainly don't want to override the dimension text.
