Thanks for the explanation.

The problem is, I want to eat my cake and have it too: I want a function (cf. 
\dynText) which combines a dynamic text with a piece of normal text and 
automatically sets the correct alignment (i.e., with the dynamic portion 
aligned as if there were no subsequent normal text), but I want to be able to 
manually tweak it afterwards (to avoid collisions, improve score aesthetics, 
etc.). Unfortunately, that "layout-time" tweak — which may be different for 
different "editions" — cannot be cooked into the function without (e.g.) 
tagging or similar content-presentation mixing, which I'd desperately like to 
avoid.

Can \dynText or similar be fashioned in such a way that leaves open the 
possibility of [effectively] tweaking the grob later in the process?

Thanks,
Kieren.
