Don’t know if that helps but you could try this AppleScript. It creates an empty formatted note with name and url, then opens it so you could paste manually.
For testing it creates the note in the current group but it can be easily changed to ask each time or to always use a specified group.
-- Create empty formatted note with name and url to paste manually
tell application "Safari"
tell current tab of window 1
set theURL to URL
set theName to name
end tell
end tell
tell application id "DNtp"
try
set theRecord to create record with {name:theName, URL:theURL, type:formatted note, source:""} in current group
open window for record theRecord
activate
on error error_message number error_number
if the error_number is not -128 then display alert "DEVONthink" message error_message as warning
return
end try
end tell
