Show data not matching the filter condition

Hello All,

Need help in power BI report query - We have multiple projects and teams working on these projects with monthly deliverables. There are some teams who do not have any projects or monthly deliverables mapped to them

When a month is selected say July, we want to see the list of teams that do not have any projects for July (they can have something completed in the month of May already but nothing for the future)

For example, If August is selected, a table should show the list of teams that have no projects or no deliverables. 

The data is structured such that only the teams having a project are mapped to these monthly deliverables/projects. But in the report we want to show what is not mapped instead of what is mapped.

What can be done in Power BI to achieve this?

Thanks
