How to plot to two figures simultaneously?

Here's the idea:
I'm making a live script to be printed and submitted for uni. At one point, I have to plot like 20 figures. It is more convenient to plot all these on a 4x5 subplot to be quickly looked over for mistakes etc., but this isn't good for detail. I was hoping to then simultaneously plot to an invisible figure (say fig(m,"...") in a for loop m=1:20), while also plotting to this subplot, and then printing the resultant figures to (hopefully one multi-page) pdf documents. I'd then attach this to my assignment for further scrutiny.
But nothing seems to do this, and everything I search is saturated with subplot faqs.
Is this reasonable or no? I get atm I could just duplicate the code, but that kinda destroys the whole idea of simultanous coding as it will get really messy, and get quite slow, very quickly.

Hi Hugh,
Seemingly, you would like to plot to two figures, is there a reason you have not tried to do the following?
for m = 1:20 % Going through all 20 plots as above
for i = 1:2
figure(i); hold on; % Selecting which figure to plot to
if i == 1
subplot(4,5,m); % subplot as described above
end
% plot commands that you are using
end
end

Create the subplots and then copy each subplot axes to an independent figure at full size.
Here's a demo.
% Create subplot
figure()
sp(1) = subplot(2,2,1);
plot(rand(20,2), '-o')
sp(2) = subplot(2,2,2);
surf(peaks(15))
sp(3) = subplot(2,2,3);
[X,Y] = meshgrid(linspace(-2*pi,2*pi),linspace(0,4*pi));
contour(X,Y,sin(X)+cos(Y))
sp(4) = subplot(2,2,4);
histogram(randn(1,100)+10);
% copy each subplot to an independent figure
for i = 1:numel(sp)
newfig = figure();
axCopy = copyobj(sp(i),newfig);
axCopy.Position = [0.13 0.11 0.775 0.815]; % default fig pos.
end

To investigate a handle, you can determine what the handle is:
class(h) % h is the handle.
or just print h in the command window and the first line shows what the handle is (ie, "Line").
Then you can look up "Line properties" in the documentation which defines each property.
If you give titles to each subplot in my example, you'll see that the titles are copied to the figures. "I can't copy the axis to the subplot " -- my example copies an axes to a figure. Are you doing the opposite -- copying an axes to a subplot? If so, there are two ways to do that.
