Thanks! Now I understand!

How to disable "Mirror function" of the Database? Not to udpate all other mirrors/copies when one instance of the Database is filtered for example?

But if I just copy->paste it, then filters of one Database applies to all other copies of that Database..So there is no possibility like in Notion to have different views of the same Database in different pages (without affecting each other)?

Can`t find how can we Create Linked Database like in Notion. If we have some Database -> how to ReUse it on the different page? (If I want to have filtered view of the same Database?).
