After checking out the one ui 2 videos. The one feature I figured would be useful was Bixby routines. I installed the beta and cannot see any this one feature I wanted to try out.
As it stands this still isn't available for the S9/S9+ it debuted on the S10 and has been on other devices released afterwards such as the Note 10 and at least some of the A series phones
On S9+ Bixby routines are "quick commands"
Hopefully it is what you're looking for.
unfortunately the S9 models do not support Bixby Routines because of some memory issues. However, you can try to download "Routine" as a plug-in for the Good Lock app from the Galaxy Store. They are very similar features
