Formula from a formula

I have a board within the board, in one of the groups. I have a item that has a subitem that has time tracking one of its columns. That time tracking subitem column is mirrored to a column that is a formula that tallies the sum, as we can go start/stop a few times in that subtask. The column name is “total configuration time” which is a formula column.

My question is, can you take the column “total configuration time” which is again sub-item column and create a total sum of all of the entire boards, groups, items, sub-items into one column that give me total time of the whole board in months, days, hours ,sec etc
