How to populate a Drop-down property control with a list of existing Filtering Schemes?


I am trying to investigate if it's possible to build logic into the Web Player so that is able to Create and Change Filtering Schemes using property controls in a Text Area. Currently, that functionality is limited to the Spotfire Analyst.

At the moment, I am trying to figure out how to populate a drop-down property control as soon as the document is opened with the existing filtering schemes. Does anyone have any pointers on how to do that? 

Thank you in advance! 

This is what my end result will look like (after I get all the pieces to work together if it's even possible):
