Kenmore series 100 HE top loader - Fabric softener

There's no where to put fabric softener. I'm not going to sit next to my washing machine for an hour to hr and 45 min to time adding it at whatever time it's supposed to be added, because different loads take different amounts of time due to sensing, just doesn't make sense and I have no time for it.

The door also locks, so not sure if I could even open it.

I looked into the downy ball, but realized last second that it says not suitable/designed for he washing machines.

the reviews are 50/50 as to whether or not it works, but alas, no one ever mentions their type of washer outside of being HE

anyone with the washing machine find a solution, or know iof the downy ball will work ?

Model# 11020232710 I pulled the manual, and there was no help there, and I know the beads don't really soften fabric, they're more for post washing scent
