Adding a Airport name tag

I’d like to add a airport name to a small grass strip on the sim thats not listed. I know i should be using the Developers tools etc. Also would like to add our own house as a tag. I know airports and certain points of interest show up as a flag in the air above it. Just like to know how you do this if possible. Can one of you direct me to a post etc that shows how this tag can be added.

Sure would like it if someone would answer this.
