SWV 6.1 - Why creating "layer dependencies" and not use for capturing update ?

Hello, Except I miss something or trip/trick for this, we can not capture a new layer or update an existing, if this layer has a "high" dependency to another.
eg. if you create a layer for your SQL express, and you want to create another layer for your DS installation: You need the SQL running, to install your DS.
But you cannot do that because to capture a "new application", you must deactivate ALL your existing layers !
I also try to create an "empty layer", make this layer dependent from my existing "SQL layer", and try to update my "empty" hoping Altiris will start the dependent layer before starting the capture... No way ! :-(

So My request is simple - Just change this so "dependencies" can really be usefull. Now I do as before using SVS, creating multiple layers including the SQL express, instead creating a single SQL layer, a few others will link as dependent from. Best regards, & thanks your reading ! :-)
