Cloud Studio SDK: How do I replicate Standard Account Filter Functionality in OWL

Hi All

We have a requirement to replicate this functionality on our custom BO OWL. I have an association to the account and territory already but how can I create a defaultset that will function the same as 'My Account Team's Accounts' or 'My Accounts'.

I thought I could create a reuse function, get current employee login ID from context and use a transformation... however I have the limitation that my reuse function can not pass a CollectionOf to my select query transformation.

I have a feeling I need to use the businesspartnerrelationship BO? has anyone tried this?

I tried to check the standard Account SOWL but I can't find anything helpful...
