Basically, you can use found jam projects, replacing the "/Jamfile$" with 
"//stage", and e.g. add these to an alias, e.g:

-- Jamroot (partial, untested) --

path-constant all-stage : all-stage ;

alias sub-stages : sub1//stage sub2//stage ; # but generating the target 
list automatically

install stage :
    sub-stages
    :
    <location>$(all-stage) # overrides location if exists in sub-stage
    ;
