[SARA Timeseries Utility] Precipitation Disaggregation

I am trying to disaggregate daily precipitation to hourly for climate change scenario(2000~2100). However, it looks like I need hourly data from nearby stations for the same time period to utilize disaggregation function in SARA. Obviously, I don't have hourly data up to 2100 from nearby stations. Is there a way where I could disaggregate without secondary hourly stations?
