Rename all databases when doing a mongorestore?

All we need is an easy explanation of the problem, so here it is.

I have a datadump but I need to change the name of every database while restoring them,
if a database is named "customers" it needs to be "customer2", "products" to "products2"

I can rename an individual database but that will take a lot of time to rename each database separately

mongorestore --nsFrom='PetHotel.pets' --nsTo='PetHouse.pets' --nsInclude="PetHouse.*" dump/

how to I rename all database in a dump?
