Thank you for your prompt reply.
I will tell you the imagination I have.
However, I am not good at English, so I will attach a table created in Excel.
Application is Create entity 2 from entity 1 using the formula for entity 3.
Entity 3 can be edited, added and deleted by the administrator.
The number of entities 2 will always be the same as the number of entities 3.
The last table is the format that is actually displayed on the screen.
