As in the case of supra-regional radio, Play It Live could allow the creation of multiple mutations of regional streams, where for each of them it would be possible to set different advertising blocks, different jingles, news blocks, etc. Of course, these regional ads or jingles should have the same length as the advertising block or jingles in the main mutation. If the regional advertising block were a little shorter or, conversely, the main block were a little shorter, a specific song could be chosen as a filler, which would automatically fade out at the end of the regional block.
