Autoinsert two siblings under a parent

[Yves Barbion]

Hi Structured FM experts

Does anyone know whether there is a way to autoinsert two siblings under a
parent?

I have got a <menucascade> element which needs two <uicontrol> child
elements. I was wondering whether I can have these two <uicontrols>
automatically inserted as child elements whenever I insert a <menucascade>.

Thanks in advance.
