How to set smart pickers sort order?

[AlejandroSanchez90]

i don't see a clear pattern when i open smart pickers, opened buffer are randomly placed, recent files as well, is there a way to force sort by open buffers, then last accessed, and then the rest ? also is there a way to limit result by cwd? when i open smart, it gets all the files i have opened in all projects

opts = {
  picker = {
    sources = {
      smart = {
        multi = { 'buffers', 'recent', 'files' },
        sort = { fields = { 'source_id' } }, -- source_id:asc, source_id:desc
        filter = { cwd = true },
