Individual motion alert notifications

I have a lot of landscape lighting along my driveway, and the mailbox at the road at the end of the driveway. I have multiple motion sensors at entry points, so that if someone comes home at 1 am, or leaves for work before sunrise, all the lights will come on. I also have a mailbox sensor set to alert me when the mail comes in. I'd like to be able to have that sensor turn on all my landscape lighting if someone attempts to steal our mail in the middle of the night (which has been happening in our neighborhood). However, if I want to do that, I have to enable motion alerts for EVERY sensor in that light group. Doing that would create too much notification spam.I had a spotlight aimed at the mailbox that was in the light group alone with the mailbox sensor originally. That did successfully spook a would be thief at 2 am once. However, we had to cut down the tree that light was mounted in, and there's no viable replacement location to place the light. I think having my whole front yard light up would be a great deterrent.
