Report that shows a date field that = this month?

Report that shows a date field that = this month?

Is this not possible?  Trying to figure this out.  I want to make a report that shows a date field that = current month but that doesn't come u as an option.  Right now I'm picking "is between" and I pick the first and 30th of the month but that I'd have to change every month and remember to do it.  Is there any way at all to have it show current month as criteria or do I have to do it manually?

Also is there no way to change the content of an email that's scheduled with report scheduler?  I'd like to automatically send reports to my business partners, but I can't the way it is since it's just an ad for Zoho, not mentioning my company at all and then providing information for Zoho sales.  I feel since I pay for this product it shouldn't write copywrite Zoho all over everything no?
