Linking a dtsx package calling another dtsx to BPC

I'm using BPC vers. 5.0.505.

I have created inside SSIS 2005 two dtsx packages and now I want to link them to BPC by using Organize package list of Web Excel without having any problems.

Does exist a right procedure (and documented) in order to do it?

Which are the right settings to link the first dtsx that calls the second dtsx? And for linking

the second dtsx?

Which are the right settings for these pkgs inside VSTO 2005?

Any advices or tips about this subject?

Many thanks for your helps.
