"Sort by" function on Sony menu - option

[Illico]

With my KDL-46EX501 Sony Bravia TV, I browse Serviio Image/Audio/Video section folders.
For example I select in Image section: Folders --> 2011 --> 10 : all my personal photos list appears

When I press "Option" button on remote control, I have some options and one is grayed "Sort by", and when I try it display this message:
"This function is not supported by server"

Is this a DLNA function ?
Is this implies that there are some servers that support this function? (I'll try with Windows Media Server next)

Yep, Serviio doesn't support sorting.

Serviio doesn't support sorting.

Do you plan to support this ? I can open a ticket.

No, I don't
