This is nonstandard practise, and hence not easy to do cleanly (AFAIK). A 
quick&dirty fix could be to create invisible 'a' notes in the second bar; 
this would create ties (though the right end points wouldn't be 100% 
correct).

Example:
\new Staff <<
\context Voice=tie {cis2 ~ \hideNotes cis2}
\new Voice {s2 des}
>>
