How to save a fig file and re-open it with the same figure number?

Very simple question which I cannot find a simple answer to:

If I save a figure with a particular figure number as a *.fig file, is there a way to keep that figure number information when reopening the figure using openfig?

Example:

f = figure(1000);
fNumber= f.Number; %result = 1000

savefig(f,'figure1000.fig')

close(f)
clearvars

g = openfig('figure1000.fig');
gNumber = g.Number; %result = 1

This example results in fNumber = 1000 and gNumber = 1. When I save a figure, I want MATLAB to be able to open the figure exactly as it was, including the figure number. Might be missing something obvious here...

Any help is appreciated.

Try this!

f = figure(1000);
ax = axes(f);
plot(ax, randn(1001, 1)) % Let's create some data visualization!

savefig(f,'figure1000.fig')
close(f)
clearvars

g = openfig('figure1000.fig', 'invisible');
h = figure(1000);
copyobj(g.Children, h)
