I want to set change the view for the user via workflow script so that in Requirements Grid View / Details View only specifiy requirements are diaplyed.

I tried to set a filter with:

ReqFactory.Filter("RQ_TARGET_REL") = "^Releases\On-Line Banking\Release 1.0^"

but it does not seem to influence the tree / grid view. Is there a way to change the view to a specific filter in the requirements module?
