Connector label background color

[Thogek]

This may seem a relatively minor issue, but....

The label text on connector lines appears to use the "Paper" color setting ("Tools" > "Options" > "Standard Colors") as their background color.  This probably makes sense in many cases, but...

If my connector lines are between objects within a Boundary area, and that Boundary has its own background color, the connector's text's background color shows up around the text over the Boundary's background color, looking rather clumsy.

Is there a way to set the background of connector line texts (individually or, preferably, all of 'em) to be transparent?  (If not, shouldn't there be?)

I hope I'm not too unclear....
