Problem with generating csv file from logdata

I have a model with x insignals and y outsignals which I all log by checking the 'Log signal data' box in Signal Properties/Logging and accessibility. As output I get t.ex. 'logsout.ModelName.signalName'. Now I want to generate a csv file for selected input/output signals in order to use it in other tests.

My problem is that I use different scheduling for different subsystems. This results in different length for the time and data values of the logged signals, lets say length(signal1.Time)= 2000, length(signal2.Time)= 10000, length(signal3.Time)= 20000 and so on. I try to generate a csv file as following:

for i = 1:length(wantedVariables)
    try
        csvVariables{end+1,1} = evalin('base',char(wantedVariables{i}));
        nameVector{end+1,1} = csvVariables{end}.Name;
        timeVector(:,end+1) = csvVariables{end}.Time;
        dataVector(:,end+1) = csvVariables{end}.Data;
    catch
        disp('No logdata available')
    end
end 
logdata = [timeVector, dataVector];
dlmwrite(inputCSVName, logdata, '-append');

This of course does not work since the vectors have different length. Is there a way to do it more simple or do I have to create 'timeVector' and 'dataVector' in a more advanced way?

Thanks in advance
