TFMSFNCEdit question

Using Firemonkey, I'm using this control bound to a Currency field 

EditType - etFloat
KeyboardType -  DecimalNumberPad (using Android)
LengthLimit - 6
Precision - 2
Text - 0.00
TextPrompt - Extra $ Amount

What I'd like to be able to do is have it so that if the Value in the Dataset is 0.0 I'd like it to display the TextPrompt.  Any other value have it display the Value.

Possible?  How?  New Feature?


TTMSFNCEdit is not supported on Android unfortunately, we are currently looking/testing a potential workaround for this issue.
