How do I make a map specific motd? (shouldn't override the default motd)

[Wandering Dude | trade.tf]

I did make the folder a vpk (using vpk exe) and I did put it into my custom folder. it did work but it overrided the
default motd. Is there a way to make it map specific?

To edit the map-specific information that appears after the motd, add tf/maps/<bspname>.txt. You can also do tf/maps/<bspname>_<language>.txt for localized versions if you want to.
