bodeplot(), setoptions - YLabel, How to set?

I have a bodeplot and want to change the Ylabel text from Magnitude to something more descriptive

h = bodeplot(sys,w);
setoptions(h,'YLabel','MyString');

doesn't work, so I look at it with getoptions()

>> getoptions(h,'Ylabel')

ans = 

struct with fields:

String: {'Magnitude'  'Phase'}
FontSize: 11
FontWeight: 'normal'
FontAngle: 'normal'
Color: [0 0 0]
Interpreter: 'tex'

So it is a struct, but I cannot figure out how to address it properly with the way setoptions() is formatted. I tried:

setoptions(h,'YLabel(1).String','MyString') 

which doesn't work or any of the other obvious variations. so now it's bothering me. Please help!

rng("default")
sys = rss(5);
h = bodeplot(sys);
ylabel_opts = getoptions(h,'YLabel')

ylabel_opts = struct with fields:
         String: {'Magnitude'  'Phase'}
       FontSize: 11
     FontWeight: 'normal'
      FontAngle: 'normal'
          Color: [0 0 0]
    Interpreter: 'tex'

% set only the magnitude plot ylabel string (leave phase alone):
ylabel_opts.String{1} = 'MyString';
% apply the new settings:
setoptions(h,'YLabel',ylabel_opts);

so the correct answer is to build a complete YLabel struct, then replace the existing on with setoptions(). perfect! Thanks!

opts = bodeoptions;
opts.Ylabel.String = {'mymag' 'myphase'};
bodeplot(tf(1,[1 1]),opts)
