[NTG-context] script on attachment

I use

\useattachment[auto][example_show][sample.data][./sample.data] \attachment[auto]

to attach my sample data to pdf, but as this data need open by specific script. Are there any way to open the attached sample.data with my script when viewer click on it. or else I have to let them download the script and change the preference application to open it. BR Bill
