We use Zoho at our organization and we are a IT services org (not a product co). Forecasts purely work on Closing date basis as of now. 

For eg, if I have a potential with 20k$ with a closing date of 15/May, then my Q2 forecast under May would show 20k$. 

I would rather want it to reflect over a sales duration. The potential worth 20k$ would close on 15/May. But my project only starts 1/Jun and run for two months. So my actual revenue realization would be 10k$ in June and 10k$ in July. Is there a way I can achieve this in Zoho. 

Please help. Thanks.
