[CONNECT Update 16] How do I remove the units label from a Text Field?

When we create a text element we can insert a Text Field.  I want to link that text field to a coordinate of another element, say the start of a line.  I can accomplish that using the text editor dialog and then choosing the Fields Editor Dialog.  Pick a line, then choose the property (e.g. Start Point Y-coordinate) to display...

Text Field Editor

The text element created looks like this...

Coordinate Y

It's showing the Y component of the start point of the line.  The text field is terminated with the DGN model's master unit label (m).  How can I remove that label?  That is, I want to see just Y100.239 not Y100.239m.
