Hi there @Mati_Roy ! 
I think you could do that by using Interactives filters .
Based on an example I shared few days ago here is a suggestion
(You post wasn’t very clear about if you’re looking for an AND or an OR, so I put both in my sample below 
.
Note that with no concrete idea on how you’ve build your doc, this might not completely satisfy your need )
So, to filter your table first by Projects AND then by Due Dates I created 2 select-control on the canvas.
The first one is to select the projects (Select - Projects) from my tasks table (Tasks - 1) and the second one (Projects - Dates) is for the due dates of those tasks which pre-filters those due dates by the project selected in the first select control (
).
Then, the last step is to filter the table by the due dates select-control on the canvas with this formula (in my sample) :
thisRow.[Due Date].Matches([Projects - Dates])
Now, if it was to filter your table by Projects OR Due dates well, I kind of followed the same principle .
I still have 2 select-controls on canvas, one for the Projects and one for the Due Dates but they are not linked to one another.
I just then indicates in the filter options of that table to filter it by the Projects select-control OR by the Due Dates select-control .
(The formula for the Due Dates part is the same as the one above, using the appropriate select-control and table )
There might be others to do that though . But it depends on how you’ve build your doc .
I hope this helps
