All Open Trades with Core Position Trade set to On in its Annotation would go into the Open Core Positions box, and the rest into the Open Satellite Positions box.

The Open Core Positions Box will appear on the page before the Open Satellite Positions box

All Closed trades are treated as they are today.

Time estimate please.

(Note that another Feature request to have US or Canadian filters (no All)  on all pages will be coming later. You may want to take this into account when looking at this particular feature request)
