関連するレコードを結びつけたい

フローで関連するレコードを結びつけたい

ApexだとMap<Id,List<Contact>> というちょっと変わった変数を使って簡単にできそうです。
フローだと20個の分岐が必要みたい。 やっぱりApexの方が簡単だと思うな。
trigger xxxxxTrigger on Account (Before insert,Before update) {

   Set<Id> AccountSetId = new Set<Id>();

   for (Account acc : Trigger.new){
      AccountSetId.add(acc.Id);
   }
   List<Contact> conList =[SELECT Id,AccountId FROM Contact WHERE AccountId =: AccountSetId Order by AccountId,Id];
   String key_Id = '';
   Integr I = 0;
   Map<Id,List<Id>> conMap = new Map<Id,List<Id>>();
   for (Contact con : conList){
     if (I == 0 ) {
          key_Id = con.AccountId;
          List<Id> conIdList = new List<Id>();
     }
     if ( ke_Id == c.AccountId) {
        conIdList.add(con.Id);
     } else {
        conMap.put(con.AccountId,conIdList);
        key_Id = con.AccountId;
        List<Id> conIdList = new List<Id>();
        conIdList.add(con.Id);
     } 
     I = I + 1;
   }
   conMap.put(con.AccountId,conIdList);
  
   for (Account acc : Trigger.new){
      List<Id> IdList = (List<Id>)conMap.get(acc.Id);
      if (IdList !=null) {
         Integer max = IdList.size();
         for (Integer i = 0, i < max; i++) {
           if (i ==0) acc.1件目 = IdList[i];
           if (i ==1) acc.2件目 = IdList[i];
           if (i ==2) acc.3件目 = IdList[i];
           if (i ==3) acc.4件目 = IdList[i];
           if (i ==4) acc.5件目 = IdList[i];
           if (i ==5) acc.6件目 = IdList[i];
           if (i ==6) acc.7件目 = IdList[i];
           if (i ==7) acc.8件目 = IdList[i];
           if (i ==8) acc.9件目 = IdList[i];
           if (i ==9) acc.10件目 = IdList[i];
           if (i ==10) acc.11件目 = IdList[i];
           if (i ==11) acc.12件目 = IdList[i];
           if (i ==12) acc.13件目 = IdList[i];
           if (i ==13) acc.14件目 = IdList[i];
           if (i ==14) acc.15件目 = IdList[i];
           if (i ==15) acc.16件目 = IdList[i];
           if (i ==16) acc.17件目 = IdList[i];
           if (i ==17) acc.18件目 = IdList[i];
           if (i ==18) acc.19件目 = IdList[i];
           if (i ==19) acc.20件目 = IdList[i];
         }
