Afaik DEVONthink doesn’t offer a option to do it.
It’s not exactly what you’ve asked for, but I just implemented this AppleScript in my Workflow, called from Alfred.
If you want the DEVONthink Sorter Sound you’ll have to change the second shell command to the path found here Sorter Sound Location? , or just delete the line in the script. Of course you have to change “USERNAME” to your username.
set destinFolder to "/Users/USERNAME/Library/Application Support/DEVONthink Pro 2/Inbox"
tell application "Finder"
set mySelection to selection
repeat with anItem in mySelection
set itemName to POSIX path of (anItem as text)
do shell script "mv" & space & quoted form of itemName & space & quoted form of destinFolder
do shell script "afplay /Users/USERNAME/Music/Sounds/DropOK.aif"
end repeat
end tell
