Yes, as others have shown you.
You can also achieve this without creating another macro. Both the native KM macro/action "Trigger by Name", and the @DanThomas macro Execute Macro by Name (Spotlight) allow you to edit the macro you have found.
I agree with @Tom.
For me, I would use an Evernote Note which support RTF, including tables.
The advantage is that it can be displayed (triggered) in a variety of means:
- KM Action Open URL, using either the internal or web-based URL of the Note
- Spotlight search
- Evernote search
- LaunchBar search
You could also share the EN Note as a Public Note (read only) that would allow anyone with the Public URL to view the Note in a browser.
