How to add a value to the next available column or row in an array using for loop?

I am using a for loop to read in multiple points of data and want to combine into a single array.

See below for a simplified version of the code im working with.

for i = 1:5
filename = strcat(path,filenames{i});
genericdata = importdata(filename);

    Data.(genericdata.Task(1,:)).Var1(:,i) = genericdata.Var1;
    
end

This is fine when the value at generic.Task(1,:) remains the same, however this changes depending on the file imported.

As such I end up with values looking like

Data.A.Var1 = [1 1 0 0 0]
Data.B.Var1 = [0 0 1 0 1]
Data.C.Var1 = [0 0 0 1 0]

Where what I need is as below

Data.A.Var1 = [1 1]
Data.B.Var1 = [1 1]
Data.C.Var1 = [1]

You can try removing whatever elements are equal to zero:

Data.A.Var1(Data.A.Var1 == 0) = []
Data.B.Var1(Data.B.Var1 == 0) = []
Data.C.Var1(Data.C.Var1 == 0) = []
