Hello @Ibrahim_Farah and welcome to the Asana Community Forum 
There is no specific number that is needed. The Asana team is always monitoring this forum and they are aware about popular feedback requests 
They not only check the total votes but also the total views of a feedback request thread.
Since Asana does not have a public roadmap I cannot tell if and when this will be implemented.
However, what I can say is that Asana has always been and is constantly listening to their customers and implementing new features. Just have a look at all the features they launched in the last few months and also last year, which includes well-requested ones from the forum
