can you globally set different padding values for different Script grobs?

[Kieren MacMillan]

Hi all,

I want to redefine the way certain Script grobs are padded, independently — 
e.g., I might want

    staccato.padding = #0.5
    tenuto.padding = #0.6
    fermata.padding = #1.1
    etc.

Is there an elegant way of doing this?

Thanks,
Kieren.
