Filter date field while showing values base on creation date

I have a report to show a two dimensional table base on selected time frame when issue get created. Now I’d like to further filter the issues with a date available in “Submit Date” field. On the other hand if “Submit Date” field is empty then the issue will be excluded.
How do I create the new measure to replace “Issues Created”?
Current report is as below screenshot


the solution to show the issue counts by a custom date field requires the import of this field as a measure. Please, check the documentation on this feature:
