How to separate imaginary unit inside an arbitrary function?

Dear all

Have a simple problem:
have a function, say
Name[5*I*a] but want to break it into multiples:
Name[5*I*a]->Name[5]*Name[I]*Name[a]

The issue is that the standard :> rule does not work properly:
Name[5*I*a]//.{Name_[exa_*exb_]:>(Name[exa]*Name[exb]),
Name_[exa_*exb_*exc_]:>(Name[exa]*Name[exb]*Name[exc])}

yields just:
Name[5*I]*Name[a] instead of desired "Name[5]*Name[I]*Name[a]"


any suggestions?

with regards
Kostya
