Thread:Project:Support desk/Subpagename and navigation to parent sites

What should I do so that on a subpage only the title of the subpage and not the entire sitename appear. For example, "Subpage" instead of "Parentsite/Subpage".

And what should I do that there is an link list under the pagetitle? So, for example, on the "Parentsite/Subpage" site, a link to the Parentsite: > Parentsite

I hope you can help me.
