Not really, there's an undocumented ini setting for setting the default precision of a control, but not the number of decimal places...
Of course you can create your own control with the number of decimal places set to what you want. Every time you place that control you will get the number of places it was set to.
For example, attached is a numeric control with 9 decimal places. Every time you use it you'll get 9 digits of precision.
