Position a block below the other without knowing the size of the blocks?

[Yak]

Hi! I am trying to do what I believe is a simple and common task, but I can’t find a way to do it.
Let’s say I have a table "Expenses" and another one "Income"
I want to bring the data from the Expenses table and the Income table in the same "Page Designer" but obviously I don’t know the "height" of either table in advance as they change month by month. Is there a way to position one block below the other automatically?

Thanks in advance!

Currently, no.

The Page Designer block is a one page layout of elements of fixed position and size.
