Easysocial Profile Type which case do I need?

Hi SI Team

Reading the documentation here:

https://stackideas.com/docs/payplans/administrators/integrations/easysocial-profiletype

And looking at the cases 1,2 & 3.
I think case 2 is closet to mine.

Here is the twist:

As of now I have 3 plans set up:
a) BUG All Members Free Plan
b) Final Cut Pro 101.X MF (Paid)
c) Final Cut Pro 201.X BM (Paid)

This is what I want to do:
If some one signs up for PLAN (a)
Then they get put in an ES GROUP (a) BUG All Members Free Group. ONLY

If some one signs up for PLAN (b)
Then they get put in an ES GROUP (b) Final Cut Pro 101.X MF (Paid) AND (a) BUG All Members Free Group.

If some one signs up for PLAN (c)
Then they get put in an ES GROUP (c) Final Cut Pro 201.X BM (Paid) AND (a) BUG All Members Free Group.

Workflow: (1) Plan associated with > (2) App which is associated > (3) ES Profile which is associated with > (4) ES Group

My questions:

1) Can I put a subscriber of a plan into more than one Group.
eg:
ONLY (a) BUG All Members Free Group.
or
(b) Final Cut Pro 101.X MF (Paid) AND (a) BUG All Members Free Group
or
(c) Final Cut Pro 201.X BM (Paid) AND (a) BUG All Members Free Group
Bottom line no matter what happens all subscribers should always be in (a) BUG All Members Free Group.
Assuming that this is possible is it better to

2a) Make 2 Apps for each plan. An App for:
(a) ONLY
or
(b) AND (a)
or
(c) AND (a)

2b) Manage this in the ES Profile step of the work flow
Where profile:
(a) is associated with Group (a) ONLY
and
(b) is associated with Group (b) AND (a)
and
(c) is associated with Group (c) AND (a)

I am guessing that both of these scenarios should work?

Is there any difference between the two?

The main thing is that I want granular control over the different parts of the website free and paid!

Sorry for the length of this
