[Boost-build] Is it possible to make target feature value-dependent?

Hello,

I have an application consisted of few subprojects. The application can 
be built in client and admin mode, so I defined feature named 'mode' to 
handle various build requests. The problem is that one of subprojects 
can be built only in admin mode. Let's say I have following directory 
structure:

        project/
           |
           +--Jamroot
           |
           +--app1/
           |	|
           |	`Jamfile
           |
           +--app2/
           |	|
           |	`Jamfile
           |
           +--admin-mode-only/
           |	|
           |	`Jamfile

Every Jamfile contains definition for one target. If I execute 'bjam 
client admin' command in project folder I want admin and client versions 
of app1 and app2 to be built but only admin version of admin-mode-only 
appliction. If I execute 'bjam client' command in the same directory  I 
want app1 and app2 targets to be built and admin-mode-only target to be 
ignored. Is it possible to do something like that?

Thanks,
Dario
