Limitation of reports on Zoho Projects Integration

I was really excited when I found out that we could integrate our Projects & Prople data into Creator, because we thought it would allow us to use Projects as a datastore but wrap some of our workflows around our work, but we've hit some limitations. Is there any way to overcome these?

1. Can not use anything but the default report. We'd really like to visualise this data using Kanban/Calendar/etc, don't understand why if the data is in creator, we can't create reports with this data.

2. Can not bring in all tasks from Projects - have to specify a project

3. Not all fields are brought in.

Am I missing something or is there anything I can do to overcome these limitations? This would have been a game-changer for us!
