Map Manager's interpretation of point .shp-files

We have a rather simple workflow where features with certain property values in a point .shp-file needs to be translated into certain Microstation cells.

This is a task that Map Manager is a convenient tool for. However, at least with our configuration, the point .shp-file is interpreted as the type POINT_LINE. This interpretation prevents the possibility of overriding the symbology to use a specific cell.

From a different thread in this forum, I learned that my issue can be resolved by creating an .impx-file through the Import-pane on Map Interoperability and attaching this file instead of attaching the .shp-file directly.

But as the only thing I need from the .impx-file is to convey to Map Manager that the features in question are POINT_CELL rather than POINT_LINE it feels a bit cluncky and unneccesary overhead that I have to create a .impx-file for each and every .shp-file in the workflow. It would be much cleaner if I through a configuration variable could instruct Bentley Map - or at least Map Manager - to interpret point .shp-files as POINT_CELL and use a default cell as the symbology. Is this possible at the time being?
