How to schedule filled areas in groups

I’m new to Dynamo and encountered something that generally should be simple but so far could not figure it out. I’ve made a simple dynamo script to schedule the Filled Region areas - at the same time adding additional shared text parameters to name filled region as groups that I want - but what I need is a schedule of FIlled Region areas sorted by those groups in columns, not rows.
My solution was to make:
The scheduled parameter “Filled Region - 1” previous Filled Region parameter filtered by group name parameter of value=,Red area"
Adding Schedule parameter “Filled Region - 2” filtered by group name parameter of value = “Grey area”
Instead of being this single general Filled Region area - what I also need is, later on, to make other calculations with formulas using these groups.
Any Idea how to can I add this kind of atrribute.
