Need help reducing multiple oversized dimension text boxes at once

[0misclose]

I have a drawing with multiple rotated dimensions and some are quite small resulting in text being offset to the leader. I was wondering if there is an easy way to change all the text box components of the dimensions to fit the actual size of the text so that it isn't so offset from the leader without exploding all the dimensions. I've included some snap shots below for reference. There are quite a few in the file so I want to try and avoid having to do them manually one by one.

 

Any help would be greatly appreciated.

 

Regards,

Ryan

I've attached a dwg with a couple of sample dimensions. It looks like the text box of the text is quite a lot larger than the actual text and then the text is centred? When I reduce the size of the text box to suit the text it isn't offset.
