What is PROPLINK and can you use a dynamic FLOWAN expansion?

Hi Experts,

Everybody is familiar with the notorius FLOWAN property in the Account dimension.

I wonder if anybody has found a way to dynamically expand ACCOUNT & FLOW dimension in an assymetric way.

Example Account dimension:

Desired EPM-addin row expansion should then dynamically form like this:

601000     F05

                 F06

                 F07

602000    F20

                 F30

You have the option in the EPM-addin row definition to use an expansion based on a property of another dimension.
That works perfectly fine for one member, but not for multiple members.
Has anyone found a good way to work around this?

In the EPM-addin user guide, you can find a reference to a certain PROPLINK function (I guess migrated from EVDRE).

I wonder if this was able to perform this kind of expansion.

Thanks for you comments!
