Automatically change property value when changed it in master note

What I’m trying to do

I have several projects and I have for this projects a master note, where the project information is noted. there I have a property with the project status. How can I automatically change the project status in the meeting notes for example after I changed the project status in the master note?

I don’t want to sound rude, but why try to re-invent the wheel?

There have already been implemented some demo vaults where these use cases are probably taken care of.
I mentioned one lately:

Then another:

I understand that it may be too much for a user to transfer their vault or implement only parts of a demo vault and they miss some details, etc. but many people just ask a question on the forum half-heartedly, don’t give any details and their overall reading time is like 3 minutes of the forum…

thank you for your help! I will go through this demo vaults and I hope there will be a solution for my issue … and I can tell you that I exactly already searched in other vaults, forums, internet ecc. but didn‘t find my solution, maybe because I‘m too stupid … nevertheless thank you again

No, there’s nobody stupid here. Obsidian is a trade which needs work, is all.
I’d start with the first one and you can even incorporate bits (Dashboards) of it into the second one, if you like that one.
