Show tolerance on ordinate dim

The toleranced dims are imported dims.  First question, why is the .8125 imported dim placed as shown, how can I get it to be shown correctly?  Second, I want to dimension this feature with ordinate dims, so how can I get the tolerance to show up and be parametric?  I know I can edit this ordinate dim in the drawing and add the tolerance, but then it isn't parametric.  Thank you for your help.
