Creating Named Group is cumbersome by selecting elements manually. In v8i, there is 'Item set' to search and save, then to reuse. This is helpful to select elements by criteria, then use for Clash detection. Please restore this feature back.

In V8i Item sets were connected to Named groups so whenever the number of elements were increasing in the item set, the same change was happening in named group which helped to reduce the manual addition of elements.

In CE there is a search option in Explorer but there is no option to get that linked with Named group and later on Clash detection.
