Can you explain the tradition of the Ram Navami flags in Shirdi as mentioned in the context of Damu Anna's story?

The Shri Sai Satcharitra details a specific tradition that occurred during the annual Ram Navami festival in Shirdi. According to Chapter 25, two large, new flags were taken out in a procession through the village. One of these flags was provided by the Nimonkars, and the second one was provided by Damu Anna, a devout follower of Sai Baba. The text highlights that providing this flag was a regular vow for Damu Anna, which he carried out for many years with great love. The procession would commence from the house of Kondaji Sutara, the carpenter, and proceed with musical accompaniment before the long banners were ultimately tied to the two ends of the Masjid.
