articulation over tremolo repeats

[Lasse Rempe]

Hello -

in string music (at least), it is not uncommon to write articulation 
marks over tremolo repeats. E.g., you might have a quarter note, 
subdivided into 16th notes, and with 4 dots over it, possibly also 
connected by a tie. (E.g., Mozart, Symphony No. 25, second movement, bar 
17 - in some editions, anyway.)

In other words, what I am looking for is the 'tremolo repeat' 
abbreviation for

a16_.( a-. a-. a-.)

[In case this is not is not sufficiently clear, I can provide a scan if 
necessary.]

Is this already implemented in LilyPond? I couldn't find a reference in 
the manual (which, generally, I have found to be excellent).

Many thanks,

Lasse
