Assign a predefined type to Attribute stereotype

[altorion]

Hello to all.

I have created an stereotype that extends de "Attribute" metaclass.
I have also a Toolbox where you can select it and drop it over a class. It becomes created, but firstly it shows a window asking for the name and type of the attribute.

Is there any way to avoid that window, or to simply assign a default type to the attribute?

I have been inspecting the MDG technologies available by default on EA and nothing found...

Thanks!
