Configure local-in policy on an SD-WAN member interface

I'm trying to create a Local-In policy on a member interface of the SD-WAN (virtual-wan-link), but when selecting the source interface, i get the error on the right side. I don't have the option to select port1 from the list as its one of two member of the virtual-wan-link group.  Tried this in both GUI and CLI. Running 7.6.5. Any ideas on how to apply this policy to a member interface of an SD-WAN group?WAN group.
