Additional filter option on trade website (# of total rune sockets)

I'm severely missing this filter option on the trade website.

- "# of rune sockets": to filter based on the total # of rune sockets an item has.

The trade website offers a filter for # of open sockets, which doesn't help much if you can't specify how many sockets in total you're looking for.

Best example, looking at Morior Invictus body armour, I just want to see the ones that have 5 sockets in total, no matter if 0-5 of them slotted or not. Filtering on "0-5 empty rune sockets" doesn't help.
