"I cannot name each structure by hand because there are hundreds of them. "
I didn't mention naming the structures by hand. That would be a waste of time. Why do you mention that?
"What do you mean by actual indices?"
I mean actual indices, i.e. numeric references to specific locations in an array, e.g.:
S(1).fld = ..
S(2).fld = ..
S(3).fld = ..
% ^ Actual indices, neat, simple, very efficient.
You did not use indices, you just have some fieldnames that happen to have digit characters in them. Not the same thing at all (and generally more complex to process, as I suspect to be the case here too).
But as I mentioned at the bottom of my comment, your actual task might even be solved with some simpler operation. But we cannot guess what would be required for your actual goal, because of this:

@Yousra Ganouma: Follow Stephen's idea: Do not hide an index in the name of a field, but create an array instead, e.g.:
Data.EES{1}
Data.EES{2}
...
Data.Space(1).ESS{1}
Then the solution to split the data would be trivial and very efficient.
With hinding an index in the name you have decided for a representation of your data, which impedes the processing massively.

Convert the structure to a table, combine the tables, then convert back to structure.
Googling "struct2table" and "table2struct" will get you there.
