Control layout time scope blocks programmatically

I'm trying to plot two signals in different layouts using a time scope, as we do when using subplot. I got to do it programmatically. I'm creating a time scope using dsp.TimeScope(). I've already tried to modify time scope properties using this and this links, but without sucess. I saw that there is a propertie which allows layout modifications in time scopes, it is LayoutDimensions. But a cant acess it.

So, I'd like to do someting like:

subplot(211)

scope(signal1)

subplot(212)

scope(signal2)

Could you help me please ?

Thank's in advance !
