All blocks of beamerposter should be of same height

Question

I will greatly appreciate your help with this question.

I use beamerposter and want all the blocks (across various columns) to be of the same height (= max height of among all other blocks).

I came across your solution here: How to modify columns/column environments so they resize automatically to the largest column ?

However, in case of beamerposter, blocks can be located in different columns. And this trick of placing blocks inside columns and count the height does not work here.

I need somehow to fetch all blocks of all columns of the poster and compute max height (and set each block height to this value, maybe a certain parameter for blocks ?).

I imagine there should be a way to re-use a solution from here: How to modify columns/column environments so they resize automatically to the largest column ?

by nesting blocks into special dummy columns to count them and to adjust their height. I tried to play around this idea but failed in my tryings.

Can you please suggest a solution here? I will greatly appreciate your help with this question.

Thank you / John
