You are correct .. It don't work in this way.

What is the meaning of phase in transient analysis, when you 
have different frequencies?  The phase relationship between them 
is always changing.  I suppose it could be the phase at time=0, 
and translate to delay.

What you do have is "delay".  You can get what you want with SIN 
source, specifying a delay in seconds.

try delay={(phase/360)/frequency}
