Yeah, you could pretty easily make this a collections project. Just make a place for your house on google earth, add the place under some eclectic sting of numbers and letters to make it not be recognizable that it is a house, then just add that string to your place name.
There are a couple of types of projects: collection projects and traditional projects.
If you choose a collection project, all observations that meet the required criteria (e.g., they are in a specific place) will be added automatically, regardless of when the observations were created.
If you choose a traditional project, you do not need to create a place; if you want an observation to be included in the project, you add it manually. You can do this for both new observations and existing ones.
