import struct as property in App Designer

I'd like to load a struct as a .mat file into my app, input values and then save changes. I'd like to import it as a property. I can do it using:
properties (Access = private)
myStruct
end
And then loading it on startup:
function startupFcn(app)
myStruct = load('DemoStruct.mat');
end
This works and I am able to edit and save the struct, but I don't get the option of autocomplete when using app.myStruct. as a way to access the fields in the struct. Is there any way to do this? The only way I can get it to work is by manually typing and this is a pain when there are many fields and indexes at play.

The autocompletion completion uses static analysis, so the variables won’t be completed unless defined in the workspace. During editing, the field names of a struct are not known as they are unavailable in the workspace. Therefore you cannot access the members of the struc variables. But autocomplete can be used while debugging the program. A static code analysis might be misleading also, because fields can be created dynamically also.

Is there no way to load the struct into the workspace from the app?
