How to create named boundaries at key stations

We are currently running ORD CE 2021 R2 10.10.21.04

I have a corridor with 2.5m interval template drop, and key stations along the road at numerous locations such as entrances.

When i create my named boundaries along the alignment, there is no option to "ADD KEYSTATION" as there was in InRoads.

Please note that my alignment is in one file (ALIGNMENT) and referenced into another working file for the modelling (CORRIDOR)

I have read some posts about event points but they are many years old. If i could export my key stations as a text file (which i can) and then use that as a event list, but not sure if just station is enough info for a event point.

Is there not an easy way to include keystations into the named boundary generation process??

Please help, this is a major issue.
