Data in Column Used to Create Subitems with the names selected in Column

Hello,
I am trying to automate sub-item creation by using a dropdown column.
Example; In the dropdown column I have the following:

TV
*
Radio
*
Web
*
Mailers
*
etc.

I am trying to create an automation that takes a look at this column and creates sub-items based on what is chosen in the column.

The automation starts like this:
When “Name of Column (Need Sub-items)” changes and only if “Name of Column (Need Sub-items)” contains one of these labels *(TV, Radio, Web, Mailers, etc.)
Then create a subitem (This is where I have the problem)
I need the sub-item name to populate from the information in the “Name of Column (Need Sub-items)” column.

Is this possible?
