Optimized fence clipping in Connect U16 do not make any sence with references attached

Hi

I had to do new clipped areas from ground elevation information where all elements were shapes, my plan was to clip and copy  my area from reference information with the Optimized fence clipping option set to on in preferences.

and then placed fence use fence clip function with place fence/clip by element, but I had my area non planar so the fence result looks like this:

I changed my area to planar and did the same place fence/clip by element, selected my planar area:

Then I used the copy/move command (copy) and set the copy to fence and clip

But the result when copy from reference with these settings did not produce new shapes in clipped areas, so this don´t work when copying from reference information!!

I tested and noticed that this workflow If you have all the information in your active file works just fine, it clips and creates new shapes in clip boundary.

Fine, then I knew that I had to merge into master all my references i wanted to do this function.. BUT for my surprise when I selected all my references in attach reference dialog box and chose "Merge into master"

This option dialog box did also appear:

WHAT?!

There isn't an option to merge into master by fence what I know of, and when you can´t "clip fence" with merge into master command there will be no elements to needed processing Optimized "fence" clipping, merge into master copy the whole reference file to our master file as is, with no options whatever!

Have I missed something here? the same thing was also with V8 (Select Series) so this is no Connect issue what I know of.

What would make sense is that the Allow Optimized fence clipping:

Does not exist i preferences:

 Instead in every function that can activate this option, ex copy:

Best regards
