Enable dynamic selection of Parameterset Valuefiles in Sequences

I want to have the possibility to dynamically choose which Valuefile of a Parameterset i use when starting a Job/Sequence inside a Sequence. Currently you can only Propagate the Valuefile choosen when starting the Calling Sequence or choose a fixed Valuefile, I want to be able to decide during runtimetime which Valuefile to use.

With Jobcontrol this is possible and it is just not supported from the Designer GUI for Sequences. With this Feature enabled you could achive the following: 1: Save your Source System Connection in a Parameterset (where you can save the passwords encrypted), determine the sourcesystem for a sourcetable from a controltable and then start the Job with the correct Valuefile 2: Instead of using Userstatus or Flatfile (which are then read with the Execute Command activity) an single local Parameteres, you could write Parameteres to a Valuefile and then start parameterised Job with the correct Valuefile. This does already work, but not in a Multiple Instance Job environment where I may want to call a single job in parallel for serveral different tables and therefore would need different Valuefiles 3:Use several Parametersets (sourcesystem, stage, core, mart ...) which have the same Valuefilenames (DEV, QA, PROD ...) and just have to select on Parameter when starting a Sequence to then correctly pick the Valuefile for each Parameterset that is used

Better effectivness of the DataStage Designer, not having to use Job Control Langue for a feature that is already supported, just because it is not implemented yet into the GUI
