thank you for the idea. We are thinking about MDB features like this in future EMX10, but so far I can not give you a definite date.
We will discuss it in our development group and I will add it to our customer's wishlist. We always have to check our free resources for implementing something like this.
Currently, we are working on the EMX9 M010 release which will be available at the end of the year.
In this version you will find some new handy features: e.g. The Waterline Designer, New and improved components for both inch and mm, definition of ejector pins in part mode, some new options and a improved mold base definition dialog.
If you have any other issues or ideas for EMX you can simply write me a email
