How to specify slide order when generating plots and exporting to new powerpoint presentation?

My code creates a ppt presentation that it populates with figures created from data pulled from excel. The total slide count is ~250 with two figures per slide, but the slide order is reversed from how it is needed. How can I reverse the order or specify slide order when generating and populating slides within a newly created powerpoint presentation? Applicable code below:

h = actxserver('PowerPoint.Application');

h.Visible = 1;

h.Presentation.invoke;

Presentation = h.Presentation.Add;

---GENERATE DATA & FIGURES--- within this part of the code and within a for loop I have the following for generating and populating slides:

filename = strcat(folder,'_',num2str(thou)); %name new figure file

cfilename = strcat('Test0_',num2str(thou),'.jpg'); %create file name for each control iteration to compare with current iteration visually

saveas(fig,fullfile(fname,filename),'jpg'); %save new figure file as jpg

jfilename = strcat(filename,'.jpg'); %create full file name for saved image to be used in ppt import

close(fig) %close figure

Presentation.Slides.invoke;

blankSlide = Presentation.SlideMaster.CustomLayouts.Item(1);

Slide = Presentation.Slides.AddSlide(1,blankSlide);

Image1 = Slide.Shapes.AddPicture(fullfile(fname,cfilename),'msoFalse','msoTrue',75,75,400,400);

Image2 = Slide.Shapes.AddPicture(fullfile(fname,jfilename),'msoFalse','msoTrue',475,75,400,400);

Thanks
