Is there a way to refer to elements in Matlab App using variables?

I have the following section of code, and I wanted to try and shorten it significantly using for loops, but I haven't found a way:
app.Button_1_1.Text = app.images(app.grid(1,1),1);
app.Button_1_2.Text = app.images(app.grid(1,2),1);
app.Button_1_3.Text = app.images(app.grid(1,3),1);
app.Button_2_1.Text = app.images(app.grid(2,1),1);
app.Button_2_2.Text = app.images(app.grid(2,2),1);
app.Button_2_3.Text = app.images(app.grid(2,3),1);
This continues on for around hundred lines to get every button that I'm using. I was thinking of doing something like as follows, but I haven't found anything that works:
for r = 1:3
for c = 1:3
app.Button_r_c.Text = app.images(app.grid(r,c),1);
end
end
Is there a way to do this, or another way to shorten the process? Thanks in advance

for r = 1:3
  for c = 1:3
      app.(sprintf('Button_%d_%d',r,c)).Text = app.images(app.grid(r,c),1);
  end
end

for r = 1 : 3
for c = 1 : 3
app.Button(r,c).Text = app.images(app.grid(r,c),1);
end
end
