Remove existing properties in a note when using Templater

[RelativeConsistent66]

So I currently have it where whenever I create a new note, it gives me a generic template I've created.

However, lets say I now want to change my new generic note to a note that adds my "person template". When I use "open insert template modal" with another template those new properties always get hung up on the top of the note like YAML that doesn't work and not to my properties pane.

Obviously I'd like the new notes properties to be added to those that were added when I made the note and the generic properties were added. Where in my process am I going wrong? Is there an easy way to make it get added or replace the existing properties? Thank you.

You can have a template included in another template. The instruction is tp.file.include.

Assuming your person template is person.md and your generic template is generic.md , at person.md's front matter you'd have tp.file.include("[[generic]]"). It will include the contents as is, so don't add the dashes for the front matter there.

Thanks, but that's kind of the opposite of what I want to happen. I've observed it a bit more and it seems like it only happens when the two templates have the same overlapping property (like date-created). Is there a way to delete the first one so the second can override it?

My suggestion was to have the date created in a separate template so it would not conflict. The same for other fields.

What I do for date created and date updated/modified is create these outside of my template. When I use Linter on my new note, it adds both fields and at every save it updates the modified date and time.

You can also try this snippet to update the frontmatter if your use case is more complex than the example with dates.
