[feature request]: `format selected range` with diagnostic-languageserver

[hereGittyGitty]

Hi iamcoo,

thx a lot for 'diagnostic-languageserver'. I am trying to format visually selected python code with black or autopep8. Whenever I try to trigger the formatting with the mapping

vmap <leader>p  <Plug>(coc-format-selected)
nmap <leader>p  <Plug>(coc-format-selected)

I get the following error:

Notification error: formatSelected [ 'V' ] Error: formatRange provider not found for current buffer, your language server doesn't support it.

Formatting the whole file with the command

command! -nargs=0 Format :call CocAction('format')

works without a problem.

I did not find any related issues neither here on this site nor by using Google. Therefore I guess it must be a problem that might be only affecting me?

Here is the diagnostic-languageserver part of my coc-settings.json file that looks as unspectacular as my formatting mappings above:

Thank you very much for any help. If you need any more input just ask.

It's possible but not support yet.

Good to know so I will stop trying. Are there any plans to implement that feature in the near future? Otherwise I will look for an alternative for that exact feature in the meantime. Do you want me to create some kind of enhancement issue?

No plan yet, I don't have time to do that.
