                        ONLY_ONE
                      | 
                     Only one creative from a line item can serve at a time. | 
                        ONE_OR_MORE
                      | 
                     Any number of creatives from a line item can serve together at a time. | 
                        AS_MANY_AS_POSSIBLE
                      | 
                     As many creatives from a line item as can fit on a page will serve. This could mean anywhere from one to all of a line item's creatives given the size constraints of ad slots on a page. |

                      | 
                     All or none of the creatives from a line item will serve. This option will only work if served to a GPT tag using SRA (single request architecture mode). |

                      | 
                     A master/companion CreativeSet roadblocking type. A LineItem.creativePlaceholders must be set accordingly. |
