Can you describe Damu Anna's specific role in the Ram Navami festival in Shirdi as mentioned in the text?

Damu Anna played a significant role in the annual Ram Navami festival in Shirdi. As detailed in Chapter 25 of the Sai Satcharitra, two large new flags are taken out in a procession through the village. One of these flags belonged to Damu Anna, and the other to the Nimonkars. This was a regular vow he had undertaken for many years, which he carried out with uninterrupted love and devotion. The procession for these flags would commence from the house of Kondaji Sutara, the carpenter, and would be accompanied by musical instruments before the long banners were tied to the two ends of the Masjid.
