Thanks for the input so far
You can't input a/d's as turning points because the route format follows the ICAO Flight Plan format. You can't put a/d's into a FP so you can't do it here. Frustrating but logical.
Re the dates thing. You don't necessarily need to put in the validity period. If you leave it blank you will get all NOTAM for 48 hours from when you click the SUBMIT button. Also if you use the Briefing Handbook you can re-use a brief or choose UPDATE to only get anything that has changed since you took the brief.
Keep 'em coming!
