Dynamics and tempo alignment?

[Kevin Cole]

Hi,

I think I'm making great strides with my wee little transcriptions,
but here's my latest puzzle:

I have the following measure:

      g2^\>\tempo \markup { \italic "Slower." } 4 = 65
      <<
        { \voiceOne fs8\!\p([ g8]) }
        \new Voice
        { \voiceTwo fs8 g8 }
      >>
      \oneVoice                                              | %  20

I want the "Slower (♩= 65)" to appear above and at the start of the
decrescendo. But instead it appears to the right of it. (See attached
PNG.)  There seem to be a lot of different -- and to me -- overly
complicated -- ways of doing this. Is there a "recommended" way
without trying to give relative coordinates to move to?

Thanks.
