I am using the app designer to create an app with quite a lot of properties here is a smal sample:
MemValue_1_1 matlab.ui.control.EditField
MemValue_1_2 matlab.ui.control.EditField
MemValue_1_3 matlab.ui.control.EditField
MemValue_1_4 matlab.ui.control.EditField
MemValue_1_5 matlab.ui.control.EditField
MemValue_1_6 matlab.ui.control.EditField
MemValue_1_7 matlab.ui.control.EditField
MemValue_1_8 matlab.ui.control.EditField
MemValue_1_9 matlab.ui.control.EditField
MemValue_1_10 matlab.ui.control.EditField
MemValue_1_11 matlab.ui.control.EditField

MemValue_1_49 matlab.ui.control.EditField
MemValue_1_50 matlab.ui.control.EditField
MemValue_1_51 matlab.ui.control.EditField
MemValue_1_52 matlab.ui.control.EditField
MemValue_1_53 matlab.ui.control.EditField
MemValue_1_54 matlab.ui.control.EditField
MemValue_1_55 matlab.ui.control.EditField
MemValue_1_56 matlab.ui.control.EditField
MemValue_1_57 matlab.ui.control.EditField
MemValue_1_58 matlab.ui.control.EditField
MemValue_1_59 matlab.ui.control.EditField
MemValue_1_60 matlab.ui.control.EditField
MemValue_1_61 matlab.ui.control.EditField
MemValue_1_62 matlab.ui.control.EditField
MemValue_1_63 matlab.ui.control.EditField
MemValue_1_64 matlab.ui.control.EditField
It should be very obvious that this is bad code and I would like to use an array of MemValues but sadly due to the restrictions of the app designer I can not do that since I would need to modify the code that is not editable in the app designer. Is there any way to solve this issue?
Btw: I know that I can export to .m file where I could do that but I can not reconvert that to the .mlapp file

One thing you can do is construct the array of components in the app's startupFcn, e.g.:
N = 64;
app.MemValue = gobjects(1,N);
for ii = 1:N
app.MemValue(ii) = app.(sprintf('MemValue_1_%d',ii));
end
A new app property (here it's called 'MemValue') would also have to be added.

Not currently in R2024a or any previous release.

"the fundamental problem is, that you can not edit any code inside the createComponents in the AppDesigner CodeView"
@Moritz: I thought the problem was that you "would like to use an array of MemValues". You can do that. Let App Designer create the components one at a time as it does (using properties MemValue_1_1, MemValue_1_2, etc.), and in your startupFcn construct an array of those components, as shown in my answer.
