Dynamic Generation of Snowfakery Friend Records

Hi everyone! Long time, no see... I hope you're all doing well. :) 

I just got back into Snowfakery after a long hiatus and wanted to check if a certain fictitious scenario was possible. 

Let's say I have an object called SalesforceRoles__c which has a bunch of different fields relating to different Salesforce roles (let's say Solution Architect, Technical Architect, Business Analyst, and Developer). I have all sorts of formulas and random_choice elements set up to randomize these fields/choices dynamically and Snowfakery is generating these perfectly. I then want to create between 1-4 friend records based on which types of fields were filled in on the SalesforceRoles__c record. So, if the Business Analyst fields were filled in, I want to create a friend record of type SalesforceRoleInterest__c with Business Analyst-specific fields filled in. If the Solution Architect info was filled in, I want to create another friend record where the Solution Architect-specific fields are filled in, etc. So, each time the recipe runs for that SalesforceRoles__c object, it can generate 1-4 friend records.

I've tried using macros for each combination of fields and then trying various types of "if" criteria to include different macros or the whole friend -> object -> macro with fields combination if certain fields are set to true on the first object.

I was hoping I could do something like this. Or maybe there's some special Python I can include?:

- friends
if ${{SFRole.BusinessAnalyst__c == 'true'}}
    - object: SalesforceRoleInterest__c
      fields:
        # fields for BA filled in 
if ${{SFRole.SolutionArchitect__ == 'true'}}
    - object: SalesforceRoleInterest__c
      fields:
        # fields for Solution Architect filled in 
Fuller Example:
- object: SalesforceRoles__c
  nickname: SFRole
  fields: 
    BusinessAnalyst__c:
      random_choice:
        True
        False
    BusinessAnalystInterests__c:
      if:
        - choice:
          when: ${{BusinessAnalyst__c=='True'}}
          pick:
            ${{fake.CatchPhrase}}
    SolutionArchitect__c:
      random_choice:
        True
        False
    SolutionArchitectInterests__c:
      if:
        - choice:
          when: ${{SolutionArchitect__c=='True'}}
          pick:
            ${{fake.CatchPhrase}}
  friends:
    - object: SalesforceRoleInterest__c
      fields:
        # fields for BA filled in 
    - object: SalesforceRoleInterest__c
      fields:
        # fields for Solution Architect filled in
