Take Markdown Note

When using Services (DTPO) is there a way to “Take Plain Note” that has .markdown as the extension instead of .txt? Once I have these plain text notes I may edit and add things to them and use markdown. Right now I have to create a new markdown note, copy the original .txt note, paste it in the new markdown note and delete the txt note.

I am not asking DT to format the note, the Take Plain Note works fine. I would like the markdown extension on these notes.

Set the keyboard shortcut for Take Note in DEVONthink > Preferences >Sorter

Select your text in any app. ⌘C copy. Open Take Note (per the shortcut) and paste with settings as follows (fill in your own title, tags, formatting):

Thank you!
