Zoho projects - workers capacity across projects

Zoho projects - workers capacity across projects

Hello,

the example is: We have a worker who's capacity is 8 hours a day. He needs to work on tasks which are in 2 different projects.

I now want to assign these tasks to him. How do I know, that he for example has already tasks which take 6 hours within the one project and only can assign him only tasks for only 2 hours and not more?

Thanks for the help!
