I am interested in creating a custom detail callout for our office. Your post above gave me a start, but instead of changing the geometry of the tag, I would like to change the text the Tag displays. I want to create a tag that allows me to only display the reference to a sheet number without referencing a drawing number (though I still want the tag to be able to be linked to drawing number). The default tag allows for Drawing Number Only display, but not Sheet Number Only. I found how to add 'Sheet Number Only' to the drop down menu in the plug in settings for the detail callouts, but I can't find where to tell the file what 'sheet number only' means.
Thanks for any help you might be able to offer!
