question about my coin collection page [Risolto]

i noticed on the "my coins" section of the site, when it takes me to my collection and gives me all the different stats of my coins (country, weight, metals), that there is no way to sort them by category. specifically i want to know which of my coins are of a certain metal. maybe i'm just missing something?

Catalogue / Search / Advanced search / Metal / My collection - in

https://en.numista.com/catalogue/index.php?mode=avance&p=1&l=&r=&e=&d=&ca=3&no=&i=&v=&m=Copper&a=&t=&dg=&w=&u=&f=&g=&c=y&tb=y&tc=y&tn=y&tp=y&tt=y&te=y&cat=y

That is an example, for Copper.
Not sure if that would help.

that's exactly what i was looking for. thank you!!
