IFX: Screws on multiple parts

Hi,

I have created a 10mm thick plate that has to be screwed onto four linear guide bearings.

In the IFX-Diaglog I selected the face of the drilling and the front and back-face of the plate. Then I selected the screw that I want to use. After that IFX asks me, if I want to create a single screw or if I want to insert the screw on all instances. I selected "insert on all instances", but the screws are only added to one of the four bearings(4 of 16 screws).

When I try to use the "reuse"-command its not possible to select the face of the drillings of the other bearings.

To create the other screws I created four new screws for every bearing. It works, but its not very nice to change the size of the screws, because I have make a change four times (for every single bearing).

Is it possible to add all the screws to all four bearings with one feature?

Maybe someone knows a better solution ? 

Thanks,

Maik
