90 days out - not 9 (you may have just forgotten the 0 when you typed it).
You can place them all at the same time IF the 90 days on all the days you want has come already. I never have bothered to do them 90 days out, there are VERY few restaurants that you need to do 90 days out (just CRT, really) so you likely won't lose anything by waiting until your last day is 90 days out and doing them all at the same time.
Does that make sense? LOL =)
