blocks with attributes that refer to other attributes

[Massimiliano-9999]

Good morning, guys.
I ask you the question: is it possible in a block to insert attributes that fill in automatically, taking as reference the value inserted in another attribute (always part of the same block) and multiplying it by a number?
example:
block with name "pippo" formed by 2 labels a and b
when inserting a x-in-a-automatic value fills b with a formula for example b=a*3

Thank you 1000 for attaching the video that was very clear, I was also trying with the data field. but I had never used the block ownership table.
