Help me define this rule please - daily archive of folders

Hi - I have an external NAS drive. I am downloading content onto my local MAC drive. I have a rule currently which allows for the immediate copy/move of items as they are completed download.
I want to know if there is a way to modify this. My rule is
Check for date added
if date added = T-1
then copy item from MAC to NAS
if date added = T-7
then delete item from MAC
else if date added = T (today)
then do nothing
end...
And also looking for a way to see if HAZEL can trigger an update library sequence to my PLEX server.
so many thanks!
