Copy columns between Entities

On an ER diagram I have several tables that all need to have a group of 6 columns that need to be included in each table. I created the 6 columns in the first table but can’t seem to find a way to copy them and then paste them in to another entity/table. The only way I have been able to do it is to duplicate the columns which adds a “2” to the end of each column name and then drag the copies to the target table and edit them to remove the “2”.

There must be a better way to do this. What am I missing?

TIA

Dear TIA,

You can right click on an entity and select Move/Copy column from popup menu to copy the columns between entities. Feel free to contact me for any help and wish you have a good day!
