Is there any way I can sum up elements from design tree???
Seriously? it is not possible or no one knows?
Not sure if this is possible but this is not an easy macro IMO.
I think the best you can do is to create a folder of specific features. This folder can contain all the features which you want to count. Just refresh the folder name every time you insert a new feature which is specific to your group. This ways all your specific features are grouped and you can get the number directly from folder name.
Hope it helps!!!
It would be real sloppy, but you could iterate through each of the features, get the feature name and see if the string contains the common string ("Amb")that you are looking for.
