My suggestion is to add an option to filter by "any" or "all" matching criteria in reports (or any other filters within Wrike)
If I want to be able to filter a job by "concept 1, concept 2 or any other dates (which are custom fields)" by due this week. It returns a blank report because the data doesn't match all of the criteria.
I could make a dashboard to somewhat pull this information and export it to excel but having this information in the system would just be so much easier for us to reference and keep coming back to and have a live version.
As a side note though, I'm unable to filter a custom field (when it is a date) by "is today, this week, last week" etc.
